Exodus 17:8–16

And Amalec came, and fought against Israel in Raphidim. 9And Moses said to Josue: Choose out men; and go out and fight against Amalec: tomorrow I will stand on the top of the hill, having the rod of God in my hand. 10Josue did as Moses had spoken, and he fought against Amalec; but Moses, and Aaron, and Hur, went up upon the top of the hill. 11And when Moses lifted up his hands, Israel overcame; but if he let them down a little, Amalec overcame. 12And Moses's hands were heavy: so they took a stone, and put under him, and he sat on it: and Aaron and Hur stayed up his hands on both sides. And it came to pass, that his hands were not weary until sunset. 13And Josue put Amalec and his people to flight, by the edge of the sword. 14And the Lord said to Moses: Write this for a memorial in a book, and deliver it to the ears of Josue; for I will destroy the memory of Amalec from under heaven. 15And Moses built an altar; and called the name thereof, The Lord, my exaltation, saying: 16Because the hand of the throne of the Lord, and the war of the Lord shall be against Amalec, from generation to generation.
