6. Lo, I will stand in that place before you, on the rock of Horeb. And you shall strike the rock, and water will go forth from it, so that the people may drink." Moses did so in the sight of the elders of Israel.
7. And he called the name of that place 'Temptation,' because of the arguing of the sons of Israel, and because they tempted the Lord, saying: "Is the Lord with us, or not?"
8. And Amalek came and fought against Israel at Rephidim.
9. And Moses said to Joshua: "Choose men. And when you go out, fight against Amalek. Tomorrow, I will stand at the top of the hill, holding the staff of God in my hand."
10. Joshua did as Moses had spoken, and he fought against Amalek. But Moses and Aaron and Hur ascended to the top of the hill.
11. And when Moses lifted up his hands, Israel prevailed. But when he released them a little while, Amalek overcame.
12. Then the hands of Moses became heavy. And so, taking a stone, they placed it beneath him, and he sat on it. Then Aaron and Hur sustained his hands from both sides. And it happened that his hands did not tire until the setting of the sun.
13. And Joshua put to flight Amalek and his people by the edge of the sword.
14. Then the Lord said to Moses: "Write this, as a memorial in a book, and deliver it to the ears of Joshua. For I will wipe away the memory of Amalek from under heaven."
15. And Moses built an altar. And he called its name, 'The Lord, my Exaltation.' For he said:
16. "The hand of the throne of the Lord, and the war of the Lord, will be against Amalek from generation to generation."
