Israel Complains for Water — Exodus 17:1–3
The Israelites continued their journey through the wilderness, moving according to the Lord’s direction. Eventually, they camped at a place called Rephidim.
But once again, they faced a basic need: there was no water.
Instead of trusting God, the people immediately began complaining against Moses.
They demanded:
“Give us water to drink.”
Moses reminded them that their argument was not really with him. Their frustration was ultimately directed toward God.
The people began questioning whether the Lord was actually with them:
“Why did you bring us up out of Egypt, to kill us and our children and our livestock with thirst?”
This was a serious spiritual problem.
God had already:
- Delivered them from Egypt.
- Opened the Red Sea.
- Destroyed Pharaoh’s army.
- Provided water at Marah.
- Given them manna and quail.
Yet another difficult circumstance caused them to question God’s presence.
Moses Cries Out to God — Exodus 17:4–6
Moses was overwhelmed by the situation.
He cried out to the Lord:
“What shall I do with this people?”
God did not tell Moses to argue with the Israelites or abandon them.
Instead, God gave him very specific instructions.
Moses was to take some of the elders of Israel and carry the staff with which God had performed miracles in Egypt.
He was then told to go to the rock at Horeb.
God promised that He would stand before Moses there.
Moses was instructed to strike the rock with his staff.
Then something extraordinary happened.
Water Comes from the Rock — Exodus 17:6–7
Moses obeyed God.
He struck the rock, and water came out so that the people could drink.
Once again, God provided for His people in the wilderness.
They had no natural source of water, but God created a source where there appeared to be none.
This miracle demonstrated that God was still with Israel.
Their circumstances had changed, but God’s presence had not.
Moses named the place Massah and Meribah, because the Israelites had quarreled and tested the Lord by asking whether He was really among them.
Their question was not simply:
“Where will we get water?”
It had become:
“Is God really with us?”
A New Threat Appears — Exodus 17:8–10
Immediately after receiving water, Israel faced another challenge.
The Amalekites came and attacked them at Rephidim.
Israel had escaped Egypt, crossed the Red Sea, survived the wilderness, and received God’s provision.
Now they had to face an enemy.
Moses appointed Joshua to lead a group of Israelite warriors into battle.
Joshua gathered the fighting men while Moses prepared to go to the top of a hill.
Moses told Joshua that he would stand above the battlefield with the staff of God in his hand.
The staff was the same one associated with God’s miraculous works.
Moses Raises His Hands — Exodus 17:10–12
Joshua went into battle against Amalek.
Meanwhile, Moses, Aaron, and Hur climbed to the top of the hill.
Something remarkable happened.
Whenever Moses held up his hands, Israel began to prevail.
But when Moses lowered his hands because he became tired, Amalek began gaining the advantage.
This made it clear that Israel’s victory was not ultimately dependent upon their military strength.
God was the One giving them victory.
But Moses could not keep his arms raised forever.
He became exhausted.
Aaron and Hur Support Moses — Exodus 17:12
Aaron and Hur noticed Moses’ exhaustion.
They found a stone for him to sit on.
Then they stood beside him and held up his hands—one on each side.
As Moses’ hands remained raised, Israel continued to prevail.
This is also a beautiful picture of partnership.
Even Moses, the great leader of Israel, became tired.
He needed other people to support him.
God could have accomplished His purpose without Aaron and Hur, but He chose to involve them.
Sometimes God strengthens us directly, and sometimes He strengthens us through the people He places beside us.
Joshua Defeats Amalek — Exodus 17:13
With Moses supported and his hands raised, Joshua and the Israelite warriors continued fighting.
Eventually, Joshua defeated Amalek and his army.
Israel experienced another deliverance.
But Moses wanted them to understand exactly where the victory had come from.
It had not come merely from Joshua’s skill.
It had not come merely from the soldiers’ strength.
The victory belonged to the Lord.
“The Lord Is My Banner” — Exodus 17:14–16
After the victory, Moses built an altar.
He called it:
“The LORD Is My Banner.”
A banner represented identity, leadership, and allegiance.
By giving the altar this name, Moses was declaring that Israel’s ultimate confidence was not in its army, weapons, or leaders.
Their confidence was in God.
The Lord was their banner.
The people had been freed by God’s power.
They had been fed by God’s power.
They had received water through God’s power.
And now they had been defended and given victory through God’s power.
The pattern was becoming unmistakable.
Why Did Moses Have to Raise His Hands?
One question naturally arises from this passage:
Why did Moses have to keep his hands raised?
The passage is not teaching that Moses’ physical hands had magical power.
The staff itself was not a magical object.
The staff represented God’s authority and power.
God had already used it as a visible sign of His miraculous power before Pharaoh.
Now, on the hill above the battlefield, it became another reminder that the victory belonged to God.
Israel needed to understand something fundamental:
They could not survive by their own strength.
They were dependent upon God for everything.
Israel’s Pattern of Dependence
Look at the pattern throughout these chapters.
When Israel was trapped in Egypt, God delivered them.
When they were trapped between Pharaoh and the Red Sea, God opened the way.
When they had no water at Marah, God provided water.
When they had no food in the wilderness, God gave manna and quail.
When they had no water at Rephidim, God brought water from the rock.
When Amalek attacked them, God gave them victory.
Again and again, Israel had to learn:
God is their provider, protector, and deliverer.
The wilderness was teaching them dependence.
“Give Us This Day Our Daily Bread” — Application
This helps us understand Jesus’ teaching on prayer.
When Jesus taught His disciples to pray:
“Give us this day our daily bread,”
He was teaching them to recognize their daily dependence upon God.
We need God not merely for the major events of life.
We need Him every day.
Jesus also taught His disciples to pray for deliverance from evil.
That connects beautifully with Exodus 17.
Israel needed God for food.
They needed God for water.
They needed God for protection.
They needed God for victory.
And we need God for our daily needs and spiritual battles as well.
Do Not Forget Your Dependence on God
It is easy to become independent when life is comfortable.
When everything is going well, we may feel that we can manage everything ourselves.
But Scripture repeatedly reminds us that our strength ultimately comes from God.
Sometimes God allows us to encounter situations where our own strength is clearly insufficient.
Not because He wants to destroy us, but because those moments reveal how deeply we need Him.
The Israelites had already seen God’s power, yet they repeatedly encountered circumstances where they had to depend upon Him again.
Final Application
Exodus 17 teaches us a simple but powerful truth:
God’s people are completely dependent upon God’s provision and power.
Israel was delivered by God’s power, fed by God’s power, given water by God’s power, and defended by God’s power.
Their story reminds us not to place our ultimate confidence in ourselves.
When we pray for daily bread, we acknowledge that we need God’s provision.
When we pray for deliverance from evil, we acknowledge that we need God’s protection.
When we face battles we cannot win by ourselves, we acknowledge that the victory belongs to Him.
So remember the altar Moses built:
“The LORD Is My Banner.”
Whatever battle we face, our confidence should not ultimately be in our own strength.
God is our provider, our protector, and the source of our victory.
