And Samuel said to Saul, "The Lord sent me to anoint you to be king over His people, over Israel; and now hearken to the voice of the words of the Lord.
...
Now, go, and you shall smite Amalek, and you shall utterly destroy all that is his, and you shall not have pity on him: and you shall slay both man and woman, infant and suckling, ox and sheep, camel and ass.
