Exodus 17

YHWH sustains Israel through thirst and battle, while their doubts and Moses’ weakness remain in view.

Israel camps at Rephidim under YHWH’s command, yet finds no water. The people quarrel with Moses and question whether YHWH is among them. God tells Moses to strike the rock at Horeb, and water comes out before Israel’s elders. Then Amalek attacks. Joshua leads the fighting while Moses holds up his hands, with Aaron and Hur supporting him until sunset. After Israel’s victory, Moses builds an altar, and YHWH declares lasting war against Amalek.

1All the congregation of the children of Israel traveled from the wilderness of Sin, starting according to the LORD’s commandment, and encamped in Rephidim; but there was no water for the people to drink.
2Therefore the people quarreled with Moses, and said, “Give us water to drink.” Moses said to them, “Why do you quarrel with me? Why do you test the LORD?”
3The people were thirsty for water there; so the people murmured against Moses, and said, “Why have you brought us up out of Egypt, to kill us, our children, and our livestock with thirst?”
4Moses cried to the LORD, saying, “What shall I do with these people? They are almost ready to stone me.”
5The LORD said to Moses, “Walk on before the people, and take the elders of Israel with you, and take the rod in your hand with which you struck the Nile, and go.
6Behold, I will stand before you there on the rock in Horeb. You shall strike the rock, and water will come out of it, that the people may drink.” Moses did so in the sight of the elders of Israel.
7He called the name of the place Massah, and Meribah, because the children of Israel quarreled, and because they tested the LORD, saying, “Is the LORD among us, or not?”
8Then Amalek came and fought with Israel in Rephidim.
9Moses said to Joshua, “Choose men for us, and go out to fight with Amalek. Tomorrow I will stand on the top of the hill with God’s rod in my hand.”
10So Joshua did as Moses had told him, and fought with Amalek; and Moses, Aaron, and Hur went up to the top of the hill.
11When Moses held up his hand, Israel prevailed. When he let down his hand, Amalek prevailed.
12But Moses’ hands were heavy; so they took a stone, and put it under him, and he sat on it. Aaron and Hur held up his hands, the one on the one side, and the other on the other side. His hands were steady until sunset.
13Joshua defeated Amalek and his people with the edge of the sword.
14The LORD said to Moses, “Write this for a memorial in a book, and rehearse it in the ears of Joshua: that I will utterly blot out the memory of Amalek from under the sky.”
15Moses built an altar, and called its name “The LORD our Banner”.
16He said, “The LORD has sworn: ‘The LORD will have war with Amalek from generation to generation.’”

Questions people ask about Exodus 17

What do Massah and Meribah mean in Exodus 17?

Massah means testing, and Meribah means quarrelling. Verse 7 ties these names to Israel’s dispute with Moses and their challenge to YHWH’s presence. Their thirst was real, but their question, “Is the LORD among us, or not?”, made the lack of water a test of God.

Why did Moses hold up his hands during the battle?

The text links Moses’ raised hand with Israel prevailing and his lowered hand with Amalek prevailing. It does not call his action prayer, though it is often understood that way. Moses takes God’s rod to the hill, and Aaron and Hur support his tired hands until sunset.

What does “The LORD our Banner” mean?

Moses gives this name to the altar he builds after Joshua defeats Amalek. A banner serves as a rallying sign for a people or army. The altar’s name identifies YHWH as the one under whom Israel fights, and the next verse declares his continuing war against Amalek.
