Genesis 21

Fear Not, For God Has Heard

8 And the child grew and was weaned. And Abraham made a great feast on the day that Isaac was weaned. 9 But Sarah saw the son of Hagar the Egyptian, whom she had borne to Abraham, laughing. 10 So she said to Abraham, “Cast out this slave woman with her son, for the son of this slave woman shall not be heir with my son Isaac.” 11 And the thing was very displeasing to Abraham on account of his son. 12 But God said to Abraham, “Be not displeased because of the boy and because of your slave woman. Whatever Sarah says to you, do as she tells you, for through Isaac shall your offspring be named. 13 And I will make a nation of the son of the slave woman also, because he is your offspring.” 14 So Abraham rose early in the morning and took bread and a skin of water and gave it to Hagar, putting it on her shoulder, along with the child, and sent her away. And she departed and wandered in the wilderness of Beersheba.

15 When the water in the skin was gone, she put the child under one of the bushes. 16 Then she went and sat down opposite him a good way off, about the distance of a bowshot, for she said, “Let me not look on the death of the child.” And as she sat opposite him, she lifted up her voice and wept. 17 And God heard the voice of the boy, and the angel of God called to Hagar from heaven and said to her, “What troubles you, Hagar? Fear not, for God has heard the voice of the boy where he is. 18 Up! Lift up the boy, and hold him fast with your hand, for I will make him into a great nation.” 19 Then God opened her eyes, and she saw a well of water. And she went and filled the skin with water and gave the boy a drink. 20 And God was with the boy, and he grew up. He lived in the wilderness and became an expert with the bow. 21 He lived in the wilderness of Paran, and his mother took a wife for him from the land of Egypt. – Genesis 21:8-21 ESV

The birth of Isaac brought great joy to Sarah and Abraham. But his long-awaited arrival also rekindled some bitter animosities that lay hidden in Sarah’s heart. For the last 14 years, she had been forced to put up with the presence of Ishmael, the son that Hagar, her handmaiden, had born to Abraham. Every time she saw him, she was reminded of her ill-fated plan to have Hagar serve as her surrogate, providing Abraham with the son she was incapable of providing. But his presence soon became a constant irritant to her. In fact, not long after his birth she had forced Abraham to send he and his mother away, hoping to rid herself of this unfortunate reminder of her own insufficiency. But God had other plans. He demanded that Hagar and her newborn son return to Abraham’s household. And while that prospect probably didn’t sit well with Hagar, God provided her with a powerful promise that served as ample motivation for her to obey.

The angel of the Lord also said to her, “I will surely multiply your offspring so that they cannot be numbered for multitude.” – Genesis 16:10 ESV

Hagar did return, and for the next 14 years she raised her son in Abraham’s household. But with the birth of Isaac, things would take a dramatic turn for the worse. Moses mentions Isaac’s weaning, which would have taken place some two to three years after his birth. So, when Ishmael had reached the age of 16 or 17, he suddenly found himself facing Sarah’s full wrath. It all took place at a celebratory feast in honor of Isaac’s weaning.

During this festive occasion, Sarah saw Ishmael “laughing.” While the Hebrew word can refer to mocking or coarse jesting, it was most commonly used to refer to laughter. There is nothing in the text that would suggest that Ishmael was making fun of Isaac. Since the overall atmosphere was that of a festival, it seems much more likely that Ishmael was simply enjoying himself. But the embittered Sarah took exception to his presence and found his behavior irritating and unacceptable. So, once again, she demanded that Abraham get rid of this thorn in her flesh.

“Get rid of that slave woman and her son. He is not going to share the inheritance with my son, Isaac. I won’t have it!” – Genesis 21:10 NLT

Sarah’s strongly worded statement speaks volumes about the state of her heart. She was a jealous and angry woman. She was vengeful and vindictive. Despite God’s incredible blessings and the miraculous gift of a son, she displayed a remarkable level of animosity and ungratefulness. While it seems quite obvious that she despised Hagar and Ishmael, her real motivation was an unwillingness to give Ishmael any hope of sharing in Isaac’s inheritance. She could care less that Ishmael was a son of Abraham and a rightful heir to the family inheritance. She was demanding that Abraham disinherit Ishmael and kick he and his mother to the curb.

Abraham’s joyful feast had suddenly turned into a disturbing family feud, and it left him troubled and torn. After all, Ishmael was his son and he had been a part of the family ever since his birth. Yet now, Abraham was facing the prospect of having to case aside one of his own children or refuse, and face the wrath of his highly volatile wife.

There had been a time when Abraham thought Ishmael would be the son through whom God would fulfill all His promises. But God had made it clear that His plan would not include Ishmael. And yet, God promised to bless Abraham’s first-born son.

“No—Sarah, your wife, will give birth to a son for you. You will name him Isaac, and I will confirm my covenant with him and his descendants as an everlasting covenant. As for Ishmael, I will bless him also, just as you have asked. I will make him extremely fruitful and multiply his descendants. He will become the father of twelve princes, and I will make him a great nation.” – Genesis 17:19-20 NLT

And, in an effort to comfort Abraham, God reiterated this promise concerning Ishmael.

“Do not be upset over the boy and your servant. Do whatever Sarah tells you, for Isaac is the son through whom your descendants will be counted. But I will also make a nation of the descendants of Hagar’s son because he is your son, too.” – Genesis 21:12-13 NLT

Basically, God was informing Abraham that Sarah’s jealousy-motivated demand was all part of His grand plan. In order for God to fulfill His plans concerning Isaac, there needed to be a physical separation of the two sons. And now, some 16-17 years after his first exile from Abraham’s home, Ishmael was old enough to survive life in the outside world. And God assured Abraham that Ishmael would not only survive, but he would thrive, eventually fathering a great nation of his own.

In a disheartening case of déjà vu, Hagar suddenly found she and her son wandering in the wilderness yet again. Abraham had graciously provided them with food and water but it was not longer before those provisions ran out.

When the water was gone, she put the boy in the shade of a bush. Then she went and sat down by herself about a hundred yards away. “I don’t want to watch the boy die,” she said, as she burst into tears. – Genesis 21:15-16 NLT

Moses’ description of this heart-wrenching scene almost portrays Ishmael as a small child, but he was likely a strapping young teenager. Yet, regardless of his age, Hagar, like any loving mother, viewed her son as innocent and helpless. She knew that it was just a matter of time before she and Ishmael succumbed to the harsh conditions of the wilderness. So, she removed herself some distance and waited for the inevitable to happen. But God had other plans.

It’s interesting to note that Moses describes Hagar as lifting up her voice and weeping. Yet, in the very next verse, he states that “God heard the voice of the boy” (Genesis 21:17 ESV). Perhaps Ishmael, like his father,  had learned to call upon the name of the Lord (Genesis 13:4). But rather than speaking to Ishmael, God addressed Himself to Hagar.

“What troubles you, Hagar? Fear not, for God has heard the voice of the boy where he is. Up! Lift up the boy, and hold him fast with your hand, for I will make him into a great nation.” – Genesis 21:17-18 ESV

God was letting Hagar know that He was watching over her son. He knew what was happening and He had a plan in place. She had no reason to worry or fear. God assured this loving mother that she could hold fast to her son because he was in the highly capable hands of his loving heavenly Father. Abraham may have disinherited Ishmael but God had not. 

In the midst of her heartache and despair, just when she thought all was lost, God showed up. And the gracious and all-merciful God gave this Egyptian handmaiden a powerful promise of future blessings on her son. He would make of Ishmael a great nation. And, as God opened Hagar’s ears to hear His promise, He opened her eyes to see the miraculous presence of a well in the middle of the wilderness.

God protected and provided for Hagar and her son. They both lived to see another day. He grew to become a mighty warrior and eventually found a wife who was an Egyptian just like his mother. Ishmael would go on to father 12 sons, just like Isaac (Genesis 25:13-16). And his descendants would eventually become the Arab nations that would prove to be a constant source of conflict for the people of Israel. This was all in keeping with the promise that God had made to Abraham sometime earlier.

He shall father twelve princes, and I will make him into a great nation.” – Genesis 17:20 ESV

And Ishmael would fulfill the promise that God had made to Hagar some 16-17 years earlier.

“This son of yours will be a wild man, as untamed as a wild donkey! He will raise his fist against everyone, and everyone will be against him. Yes, he will live in open hostility against all his relatives.” – Genesis 16:12 NLT

God was working His plan to perfection. And little did Sarah understand that her hatred for Hagar and Ishmael would produce a centuries-long feud between their two nations.

But all throughout this passage, we see the sovereign will of God being displayed as He accomplishes His plan and distributes His blessings as He sees fit. There is a method to God’s seeming madness. He knows exactly what He is doing and is not caught off guard or forced to change plans based on the actions of His fallen creatures. God sees. He hears. He acts. He orchestrates. And He methodically and systematically accomplishes His righteous purposes.

And the Lord Did As He Had Promised

1 The Lord visited Sarah as he had said, and the Lord did to Sarah as he had promised. 2 And Sarah conceived and bore Abraham a son in his old age at the time of which God had spoken to him. 3 Abraham called the name of his son who was born to him, whom Sarah bore him, Isaac. 4 And Abraham circumcised his son Isaac when he was eight days old, as God had commanded him. 5 Abraham was a hundred years old when his son Isaac was born to him. 6 And Sarah said, “God has made laughter for me; everyone who hears will laugh over me.” 7 And she said, “Who would have said to Abraham that Sarah would nurse children? Yet I have borne him a son in his old age.” – Genesis 21:1-7 ESV

Moses opens this epic chapter with the simple, yet profound words, “the Lord visited Sarah.” After all that has transpired in the preceding chapters, they come across as rather anticlimactic. This is the moment for which Abraham and Sarah have long-awaited and about which they had their fair share of doubts. God had repeatedly promised that Sarah would bear a son, and now the time had come. The long wait was over. The promise was to be fulfilled. And while Moses’ words may lack an air of excitement, they display a strong sense of God’s sovereignty and faithfulness. And three separate times in the first two verses, Moses emphasizes the faithfulness of God.

The Lord visited Sarah as he had said

…the Lord did to Sarah as he had promised

And Sarah conceived and bore Abraham a son…of which God had spoken to him

That simple statement, “and Sarah conceived” is (excuse the pun) pregnant with meaning. God had done the impossible. He had performed a miracle by creating life in Sarah’s lifeless womb. The odds had been against Sarah. When Moses first introduced her in chapter 11, he had declared her unfortunate condition.

Now Sarai was barren; she had no child. – Genesis 11:30 ESV

Yet, in the very next chapter, God had issued His call to Abraham and announced His promise to produce through him and Sarah a great nation. Abraham was 75 and Sarah was 65 at the time. And 25 years later, God had reconfirmed His promise to Abraham.

Then Abraham bowed down to the ground, but he laughed to himself in disbelief. “How could I become a father at the age of 100?” he thought. “And how can Sarah have a baby when she is ninety years old?” – Genesis 17:17 NLT

So, now Sarah’s barrenness was complicated by the curse of fruitlessness that accompanies old age.

Abraham and Sarah were both very old by this time, and Sarah was long past the age of having children. – Genesis 18:11 NLT

And Sarah seemed to believe that her long struggle with infertility had been God’s doing.

So Sarai said to Abram, “The Lord has prevented me from having children.” – Genesis 16:2 NLT

Yet, at just the right moment, according to God’s sovereign plan, Sarah conceived and bore a son. Against all odds and contrary to everything we know about human anatomy and physiology, a 90-year-old barren woman became impregnated by her 100-year-old husband and carried that baby for nine months. And Moses makes it clear that this pregnancy was the work of God. He had done what He had promised to do and He had done it according to His divine timeline. The 25-year delay had been a part of the plan. At no point along the way had God been exasperated by Sarah’s inability to get pregnant. He had not made a mistake in choosing Abraham. Sarah’s barrenness had not been an oversight on God’s part. Even when Sarah and Abraham kept attempting to come up with alternate plans to fulfill God’s promise, He kept reiterating His intentions to use the two of them.

God displayed His power and confirmed His covenant faithfulness through the miracle of Sarah’s pregnancy and her baby’s eventual birth. A year earlier, God had predicted that this moment would come and He had even provided a name for the son who would be born to Abraham and Sarah.

“Sarah your wife shall bear you a son, and you shall call his name Isaac. I will establish my covenant with him as an everlasting covenant for his offspring after him.” – Genesis 17:19 ESV

When Sarah had heard this promise from God, she had reacted with disbelief and scorn, saying, “How could a worn-out woman like me enjoy such pleasure, especially when my master—my husband—is also so old?” (Genesis 18:12 NLT). And God had calmly and patiently responded, “Is anything too hard for the Lord?” (Genesis 18:14 NLT).

Now, God had answered His own question with an irrefutable demonstration of His power that should have clearly ended all speculation regarding His faithfulness. Sarah’s barrenness proved to be no problem for God. Yes, it had caused Sarah great pain and left her questioning the faithfulness and trustworthiness of God. It had frustrated Abraham, causing him to consider and, at times, implement other strategies for becoming the father of a multitude of nations. Both Sarah and Abraham wanted what God had promised, but her barrenness seemed to be an insurmountable barrier to achieving their desire. And a quarter-century of waiting only made matters worse.

But at just the right moment, according to God’s sovereign timeline, the Creator spoke into the darkness of Sarah’s despair and brought about life. And with that life, a light broke into the darkness that permeated Abraham’s world. It would be through this child that God would fulfill His promise to Abraham.

“I will make of you a great nation, and I will bless you and make your name great, so that you will be a blessing.” – Genesis 12:2 ESV

God had clearly promised to do something significant through the offspring of Abraham. He had added, “in you all the families of the earth shall be blessed” (Genesis 12:3 ESV). This boy was destined for great things. And while he would bring great joy and comfort to Abraham and Sarah, he would become the hope of the nations. Through Isaac would come another son, whose birth would also come about through miraculous means. Centuries later, the prophet Isaiah would predict the coming of this child.

Therefore the Lord himself will give you a sign. Behold, the virgin shall conceive and bear a son, and shall call his name Immanuel. – Isaiah 7:14 ESV

And Isaiah would go on to describe the circumstances in which this child would be born.

The people who walked in darkness
    have seen a great light;
those who dwelt in a land of deep darkness,
    on them has light shone.
You have multiplied the nation;
    you have increased its joy;
they rejoice before you
    as with joy at the harvest,
    as they are glad when they divide the spoil. – Isaiah 9:2-3 ESV

The birth of Isaac brought great joy and hope to Abraham and Sarah. And in a similar, yet even more significant way, the birth of this future offspring of Abraham would bring joy to the entire world.

For to us a child is born,
    to us a son is given;
and the government shall be upon his shoulder,
    and his name shall be called
Wonderful Counselor, Mighty God,
    Everlasting Father, Prince of Peace.
Of the increase of his government and of peace
    there will be no end,
on the throne of David and over his kingdom,
    to establish it and to uphold it
with justice and with righteousness
    from this time forth and forevermore.
The zeal of the Lord of hosts will do this. – Isaiah 9:6-7 ESV

At the moment of Isaac’s miraculous birth, the 90-year-old Sarah and her 100-year-old husband found themselves basking in the joy of that momentous and long-awaited occasion. Sarah’s derisive and scornful laughter had been transformed into joyful hilarity at the sight of her miracle baby. As she held her bundle of joy in her arms, she exclaimed, “God has brought me laughter. All who hear about this will laugh with me. Who would have said to Abraham that Sarah would nurse a baby? Yet I have given Abraham a son in his old age!” (Genesis 21:6-7 NLT). And the grin on Abraham’s face must have stretched from ear to ear.

What a sense of relief and gratitude this elderly couple must have felt. And you can sense Abraham’s thankfulness in the way he faithfully subjected his newborn son to the God-ordained rite of circumcision.

Abraham circumcised his son Isaac when he was eight days old, as God had commanded him. – Genesis 21:4 ESV

God had done His part, now it was Abraham’s turn. In circumcising Isaac, Abraham was dedicating his son to God. This rite was meant to be a sign of the covenant relationship between God and Abraham’s descendants.

“This is the covenant that you and your descendants must keep: Each male among you must be circumcised. You must cut off the flesh of your foreskin as a sign of the covenant between me and you.” – Genesis 17:10-11 NLT

And God had made it clear that all those who remained uncircumcised would have no part in His future blessings.

“All must be circumcised. Your bodies will bear the mark of my everlasting covenant. Any male who fails to be circumcised will be cut off from the covenant family for breaking the covenant.” – Genesis 17:13-14 NLT

Abraham wasn’t taking any chances. He wasn’t about to curse his newborn son to a lifetime of alienation from God. He had waited too long for this moment and he knew that Isaac was the key to all that God had promised.

“I will make you extremely fruitful. Your descendants will become many nations, and kings will be among them!” – Genesis 17:6 NLT

And though Abraham had no way to comprehend the significance of this promise, the gospel of Matthew provides the future fulfillment to which it pointed.

The book of the genealogy of Jesus Christ, the son of David, the son of Abraham. – Matthew 1:1 ESV

Isaac would be a means to an end. He would be the conduit through which God would bring the ultimate blessing to the nations: Jesus Christ.
