The Lord Is My Banner

8 Then Amalek came and fought with Israel at Rephidim. 9 So Moses said to Joshua, “Choose for us men, and go out and fight with Amalek. Tomorrow I will stand on the top of the hill with the staff of God in my hand.” 10 So Joshua did as Moses told him, and fought with Amalek, while Moses, Aaron, and Hur went up to the top of the hill. 11 Whenever Moses held up his hand, Israel prevailed, and whenever he lowered his hand, Amalek prevailed. 12 But Moses’ hands grew weary, so they took a stone and put it under him, and he sat on it, while Aaron and Hur held up his hands, one on one side, and the other on the other side. So his hands were steady until the going down of the sun. 13 And Joshua overwhelmed Amalek and his people with the sword.

14 Then the Lord said to Moses, “Write this as a memorial in a book and recite it in the ears of Joshua, that I will utterly blot out the memory of Amalek from under heaven.” 15 And Moses built an altar and called the name of it, The Lord Is My Banner, 16 saying, “A hand upon the throne of the Lord! The Lord will have war with Amalek from generation to generation.” – Exodus 17:8-16 ESV

After miraculously providing water for His disgruntled and dissatisfied people at Rephidim, God followed that gracious act with a much more dangerous and deadly demonstration of His power that also served to validate Moses’ role as His chosen leader. To quench their thirst and assuage their anger, God ordered Moses to use his staff to strike “the rock” so that it gushed forth water. This blatant demonstration of divine authority, accomplished through God’s official spokesman, was intended to bolster Moses’ credibility and credentials among the people.

“Pass on before the people, taking with you some of the elders of Israel, and take in your hand the staff with which you struck the Nile, and go. Behold, I will stand before you there on the rock at Horeb, and you shall strike the rock, and water shall come out of it, and the people will drink.” – Exodus 17:5-6 ESV

God allowed Moses to play a significant role in meeting the people’s need for water. It would have been just as easy for God to cause water to spring up from the dry ground, but He chose to deliver this miracle through Moses. And one of the lessons God wanted the Israelites to learn was that Moses was His personal representative. Moses spoke and acted on behalf of God. And by questioning the quality of Moses’ leadership, they were actually raising doubts about the reliability of Yahweh Himself. In a sense, their anger-filled rants against Moses were really a vocalization of their lack of faith in God.

…the people of Israel argued with Moses and tested the Lord by saying, “Is the Lord here with us or not?” – Exodus 17:7 NLT

So, with the people’s thirst temporarily satisfied, God brought a new and even more demanding trial for the people to endure. This time, the problem wouldn’t be a lack of water or meat, but it would be an overabundance of enemies.

While the people of Israel were still at Rephidim, the warriors of Amalek attacked them. – Exodus 17:8 NLT

The timing of this attack is impeccable and thoroughly ordained by God. The people had just satisfied their thirst with water from the rock when suddenly and as if out of nowhere, a force of Amalckite warriors descended upon them.

The Amalekites were a nomadic people who had descended from Esau, the son of Isaac and the twin brother of Jacob.

These are the descendants of Esau who became the leaders of various clans:

The descendants of Esau’s oldest son, Eliphaz, became the leaders of the clans of Teman, Omar, Zepho, Kenaz, Korah, Gatam, and Amalek. – Genesis 36:15-16 NLT

These descendants of Esau were close relatives of Israelites who had settled in the southern region of Canaan, between the border of Egypt and Mount Sinai. During the Israelites’ 400-year sojourn in Egypt, the Amalekites had grown in number and considered the wilderness of Sin as their homeland. The scene of millions of Hebrew refugees setting up camp on their home turf must have alarmed the Amalekites. Water rights and pasture land would have been of great value in that arid part of the world. So, the Amalekites decided to give the Israelites ample reason to move on.  But rather than ordering the Israelites to run, Moses put together a battle plan, formed a makeshift army, and assigned a young man named Joshua to serve as commander. Then he gave this new general his strange-sounding strategy for achieving victory.

“Choose some men to go out and fight the army of Amalek for us. Tomorrow, I will stand at the top of the hill, holding the staff of God in my hand.” – Exodus 17:9 NLT

The Israelites were shepherds, not warriors. None of them had any military training or battle experience. Yet, Moses was ordering them to go up against an Amalekite force comprised of seasoned and well-equipped warriors.

So, the next day, as Joshua led his rag-tag group of citizen soldiers into battle, Moses ascended a nearby hill in the company of Aaron and Hur. There on the mountaintop, Moses took the very same staff he had used to strike the rock and raised it above his head with both arms. The text states that, as long as he held the staff aloft, the Israelites were able to get the upper hand in the battle taking place in the valley below. But as time wore on, Moses’ arms grew weary, and as he lowered them to rest, the battle went in favor of the Amalekites. The key to victory over the Amalekites was directly tied to God’s chosen leader raising his staff over the enemies of Israel.

In the heat of the battle taking place in the valley, Joshua had no way of knowing what was happening on the mountaintop. One minute his forces gained the advantage, only to find themselves retreating in apparent defeat. It was a touch-and-go affair that could go either way. 

But Moses’ two companions could see exactly what was going on and knew that they were going to have to intervene or the battle would end in tragedy. Moses was insufficient for the task. He had the heart and possessed the staff through which the power of God was displayed, but he lacked the stamina necessary to stay the course.

Moses’ arms soon became so tired he could no longer hold them up. So Aaron and Hur found a stone for him to sit on. Then they stood on each side of Moses, holding up his hands. So his hands held steady until sunset. – Exodus 17:12 NLT

The power of God was more than sufficient to meet the need. What was lacking was Moses’ ability to serve as the unwavering conduit through whom God’s power could flow unchecked. God’s chosen leader was well into his 80s when this battle took place and the physical demands on his elderly body proved to be too much. He understood that victory hinged on his ability to keep the staff aloft but he lacked the personal strength to do his part. That’s when Aaron and Hur stepped in. These two men immediately understood the role they were there to play.

First, they provided a stone on which Moses could rest. The exhausted octogenarian was completely worn out from the physical exertion and the emotional toll he suffered every time he lowered his arms and watched the battle turn against Joshua and his troops.

Next, they each stood alongside Moses, lifting his arms into the air and using their combined strength to serve as conduits of the power of God. The staff remained aloft, the power of God flowed, and the army of Israel won the day.

Joshua overwhelmed the army of Amalek in battle. – Exodus 17:13 NLT

In the aftermath of this great victory, God ordered Moses to make a permanent record of this victory, along with a promise regarding the eventual destruction of the Amalekites.

“Write this down on a scroll as a permanent reminder, and read it aloud to Joshua: I will erase the memory of Amalek from under heaven.” – Exodus 17:14 NLT

God specifically told Moses to deliver this divine promise to Joshua. It was as if God was letting Joshua know that this battle was far from over. They had not destroyed the Amalekites but had simply defeated them in battle. That meant they would live to fight another day. But God wanted Joshua to know that he would lead one more battle against these enemies of Israel and, when that day came, Joshua would have the pleasure of wiping them off the face of the earth.

This promise would not take place until long after the Israelites had entered the land of Canaan and made it their own. Some forty years later, Moses would pull out his written record of God’s promise and read it to Joshua again.

Therefore, when the Lord your God has given you rest from all your enemies in the land he is giving you as a special possession, you must destroy the Amalekites and erase their memory from under heaven. Never forget this! – Deuteronomy 25:19 NLT

And at the scene of the battle, Moses erected another record of their decisive victory. He erected an altar anbd named it Yahweh-Nissi (which means “the Lord is my banner”). This memorial or tribute to God’s faithfulness celebrated His sovereign role in Israel’s victory. Moses, Aaron, and Hur were simply instruments in God’s hands. Joshua and the men who fought alongside him, each served under the banner of the King of kings. They were the army of God Almighty. But the victory was God’s alone.

And Moses recognized that the Amalekites would pay dearly for their decision to stand against the God of the universe. Their assault on the Israelites was a direct attack on the sovereignty of Yahweh, the ruler of heaven and earth. And God would hold the Amalekites accountable for their actions.

“They have raised their fist against the Lord’s throne, so now the Lord will be at war with Amalek generation after generation.” – Exodus 17:16 NLT

Doubting God’s Presence

1 All the congregation of the people of Israel moved on from the wilderness of Sin by stages, according to the commandment of the Lord, and camped at Rephidim, but there was no water for the people to drink. 2 Therefore the people quarreled with Moses and said, “Give us water to drink.” And Moses said to them, “Why do you quarrel with me? Why do you test the Lord?” 3 But the people thirsted there for water, and the people grumbled against Moses and said, “Why did you bring us up out of Egypt, to kill us and our children and our livestock with thirst?” 4 So Moses cried to the Lord, “What shall I do with this people? They are almost ready to stone me.” 5 And the Lord said to Moses, “Pass on before the people, taking with you some of the elders of Israel, and take in your hand the staff with which you struck the Nile, and go. 6 Behold, I will stand before you there on the rock at Horeb, and you shall strike the rock, and water shall come out of it, and the people will drink.” And Moses did so, in the sight of the elders of Israel. 7 And he called the name of the place Massah and Meribah, because of the quarreling of the people of Israel, and because they tested the Lord by saying, “Is the Lord among us or not?” – Exodus 17:1-7 ESV

Since leaving Egypt, the Israelites have displayed a clear pattern of behavior when encountering what they believe to be unexpected and undesirable difficulties. As soon as things take a perceived turn for the worse, they express their disapproval to Moses and Aaron. At Marah, they discovered that the water was undrinkable, so they took their dissatisfaction with the situation to the two brothers.

So the people murmured against Moses, saying, “What can we drink?” – Exodus 15:24 NLT

Rather than reprimand them for their mistreatment of His appointed leaders, God miraculously transformed the bitter water of Marah into fresh drinking water. But He also gave them a warning about their ongoing behavior. He demanded that they begin to do what is right and obey His commands or they could find themselves suffering some of the same plagues that befell the Egyptians. His constant care for them came with conditions.

Not long after that event, as the people made their way through the desolate wilderness of Sin, their supply of unleavened bread ran out, and their growing hunger caused them to lash out in frustration yet again.

The entire company of Israelites murmured against Moses and Aaron in the wilderness. The Israelites said to them, “If only we had died by the hand of the Lord in the land of Egypt, when we sat by the pots of meat, when we ate bread to the full, for you have brought us out into this wilderness to kill this whole assembly with hunger!” – Exodus 16:2-3 NLT

Once again, God intervened and performed yet another miracle. He provided them with quail each evening and a bread-like substance every morning that would supply all their nutritional requirements for the rest of their journey. But just days later, when the people arrived at a place called Rephidim, they found another reason to complain. There was no water. It seems that the water they had gathered at Marah had run out and now Moses and Aaron had led them to yet another desolate and dry spot that provided no hope of quenching their thirst. So…

…the people were very thirsty there for water, and they murmured against Moses and said, “Why in the world did you bring us up from Egypt—to kill us and our children and our cattle with thirst?” – Exodus 17:3 NLT

In each successive encounter, their complaints become increasingly darker and more desperate. Their inflammatory rhetoric reflects their growing disillusionment with the entire enterprise. They expressed their regret of having ever left Egypt and accused Moses and Aaron of leading them on a virtual death march into the God-forsaken wilderness.  

The further they got from Egypt and the closer they got to Canaan, they began to second-guess the leadership of Moses and the reliability of Yahweh. Despite all that God had done for them, they questioned the very nature of His “deliverance” by declaring it to be headed to certain failure. In their minds, each difficulty they faced provided further evidence that this problem-plagued trip to the promised land had been a huge mistake.  

Driven by thirst and fear, they accused Moses of trying to kill them. Their deliverer had become their executioner. But what they failed to understand was that Moses was simply following directions. He was being guided by the pillar of cloud by day and the pillar of fire by night. These manifestations of God’s presence were always with them and had been guiding them all along the way. Their arrival in Marah had not been a mistake. God had led them to a place where the water was undrinkable. He had known all along that their bread would eventually run out and their hunger would cause them to question His goodness.

God was not lost. He had not become disoriented in the trackless wilderness of Sin. He knew exactly where He was going and what He was doing. He was testing His people to see if they would trust Him. He was placing them in situations that were designed to expose their doubts and fears. And here in Rephidim, He provided them with yet another test of their confidence in Him. There was no water. But the pillar of cloud remained at the head of their column. As they made camp, the divine presence of God was visible for all to see. He had not left them or forsaken them.

But the people had their doubts. They could not understand why this God of Moses and Aaron would allow them to suffer. If this Yahweh was so powerful and great and if He truly was with them, why did they keep ending up in less-than-satisfactory situations? Did He not know that Rephadim had no water source? But rather than take their questions and concerns to God, they turned on Moses and Aaron, and their anger was so intense that Moses feared for his life.

“What will I do with this people?—a little more and they will stone me!” – Exodus 17:4 NLT

But, once again, God intervened. He gave Moses the following instructions:

“Go over before the people; take with you some of the elders of Israel and take in your hand your staff with which you struck the Nile and go. I will be standing before you there on the rock in Horeb, and you will strike the rock, and water will come out of it so that the people may drink.” – Exodus 17:5-6 NLT

God could have acted on His own, but He chose to use His servant Moses as the means of addressing their perceived problem. As the elders looked on, the pillar of cloud moved from the camp and repositioned itself above a particular rock. In a desert filled with rocks, this relocation of God’s divine presence provided Moses with a clear indication as to which rock he was to strike. Not just any rock would do. In fact, God clearly indicates that His presence will reside over “the rock” in Horeb.

This rock had already been set apart by God as the source of their sustenance. He had known all along that Rephidim would be an arid region devoid of water. But “the rock” was already in place and ready to deliver what the people needed. So, when Moses obeyed the command of the Lord and struck the rock, water poured from it in a steady stream. That ordinary-looking rock became a source of life-giving refreshment in the midst of a barren wilderness. And it became a symbol of God’s salvation that, centuries later, the apostle Paul would use as a foreshadowing of Jesus

I don’t want you to forget, dear brothers and sisters, about our ancestors in the wilderness long ago. All of them were guided by a cloud that moved ahead of them, and all of them walked through the sea on dry ground. In the cloud and in the sea, all of them were baptized as followers of Moses. All of them ate the same spiritual food, and all of them drank the same spiritual water. For they drank from the spiritual rock that traveled with them, and that rock was Christ. Yet God was not pleased with most of them, and their bodies were scattered in the wilderness. – 1 Corinthians 10:1-5 NLT

This divine deliverance would be repeated multiple times during the peoples’ wilderness journey. God delivering water from a rock would become a symbol of His providential care and life-sustaining power. Even in the midst of a waterless desert, God could provide salvation from the most unlikely of sources. But would the people trust Him? Would they stop judging His character based on the nature of their surroundings?

God knew that the real problem with the people was not a lack of water, but a lack of trust. Despite the pillar of cloud, the manna and quail, and the miracle at Marah, the Israelites continued to doubt the presence of God.

…they tested the Lord by saying, “Is the Lord among us or not?” – Exodus 17:7 ESV

And to commemorate this place of testing, Moses gave it two different names: Massah and Meribah. Massah means “place of testing” and Meribah means “place of murmuring or discontentment.” It was a place of testing because the people tested the patience of God. But it was also a place where God tested the faith of His people and, sadly, they failed. Rather than recalling God’s past provision in times of difficulty, they murmured and complained. Instead of trusting in God’s proven ability to provide for all their needs, they allowed present circumstances to raise doubts about His power and presence.

Reluctantly and rather slowly, they were learning to trust in God. He was sufficient to supply all their needs. There was no circumstance too dire, no enemy too great, or difficulty too large that God could not overcome. But that lesson would take years for the Israelites to learn.
