Exodus 17:8–16

^8lThen came Amalek, and fought with Israel in Rephidim. ⁹And Moses said unto ^mJoshua, Choose us out men, and go out, fight with Amalek: to morrow I will stand on the top of the hill with ⁿthe rod of God in mine hand. ¹⁰So Joshua did as Moses had said to him, and fought with Amalek: and Moses, Aaron, and Hur went up to the top of the hill. ¹¹And it came to pass, when Moses held up his hand, that Israel prevailed: and when he let down his hand, Amalek prevailed. ¹²But Moses’ hands were heavy; and they took a stone, and put it under him, and he sat thereon; and Aaron and Hur stayed up his hands, the one on the one side, and the other on the other side; and his hands were steady until the going down of the sun. ¹³And Joshua discomfited Amalek and his people with the edge of the sword. ¹⁴And the Lord said unto Moses, ^oWrite this for a memorial in a book, and rehearse it in the ears of Joshua: for ^pI will utterly put out the remembrance of Amalek from under heaven. ¹⁵And Moses built an altar, and called the name of it ^||Jehovah-nissi: ¹⁶For he said, ^||Because ^†the Lord hath sworn that the Lord will have war with Amalek from generation to generation.
