Then came Amalek, and fought with Israel in Rephidim.
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.
Now go and smite Amalek, and utterly destroy all that they have, and spare them not; but slay both man and woman, infant and suckling, ox and sheep, camel and ass.
