Then came Amalek, and fought with Israel in Rephidim.

And Moses said unto Joshua, Choose us out men, and go out, fight with Amalek: to-morrow I will stand on the top of the hill with the rod of God in my hand.

So 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.

And it came to pass, when Moses held up his hand, that Israel prevailed; and when he let down his hand, Amalek prevailed.

And Joshua discomfited Amalek and his people with the edge of the sword.

And Jehovah said unto Moses, Write this for a memorial in a book, and rehearse it in the ears of Joshua: that I will utterly blot out the remembrance of Amalek from under heaven.

And he said, Jehovah hath sworn: Jehovah will have war with Amalek from generation to generation.
