5. And the Lord said to Moses, “Go on before the people, and take with you some of the elders of Israel. Also take in your hand your rod with which you struck the river, and go.
6. Behold, I will stand before you there on the rock in Horeb; and you shall strike the rock, and water will come out of it, that the people may drink.”And Moses did so in the sight of the elders of Israel.
7. So he called the name of the place Massah and Meribah, because of the contention of the children of Israel, and because they tempted the Lord, saying, “Is the Lord among us or not?”
8. Now Amalek came and fought with Israel in Rephidim.
9. And Moses said to Joshua, “Choose us some men and go out, fight with Amalek. Tomorrow I will stand on the top of the hill with the rod of God in my hand.”
10. So Joshua did as Moses said to him, and fought with Amalek. And Moses, Aaron, and Hur went up to the top of the hill.
11. And so it was, when Moses held up his hand, that Israel prevailed; and when he let down his hand, Amalek prevailed.
12. But Moses’ hands became heavy; so they took a stone and put it under him, and he sat on it. And Aaron and Hur supported his hands, one on one side, and the other on the other side; and his hands were steady until the going down of the sun.
13. So Joshua defeated Amalek and his people with the edge of the sword.
