Then the Lord said to Moses: Write this down in a book as something to be remembered, and recite it to Joshua: I will completely blot out the memory of Amalek from under the heavens.
Therefore, when the Lord, your God, gives you rest from all your enemies round about in the land which the Lord, your God, is giving you to possess as a heritage, you shall blot out the memory of Amalek from under the heavens. Do not forget!
