1 Samuel 15:2-3

15:2 Here is what the Lord of hosts says: ‘I carefully observed how the Amalekites opposed Israel along the way when Israel came up from Egypt. 15:3 So go now and strike down the Amalekites. Destroy everything that they have. Don’t spare them. Put them to death – man, woman, child, infant, ox, sheep, camel, and donkey alike.’”
