1 Samuel 15:2-3

Thus says the  Lord of hosts, ‘I have noted what Amalek did to Israel a in opposing them on the way when they came up out of Egypt. Now go and strike Amalek and b devote to destruction
That is, set apart ( devote) as an offering to the Lord (for destruction); also verses 8, 9, 15, 18, 20, 21
all that they have. Do not spare them d but kill both man and woman, child and infant, ox and sheep, camel and donkey.’”
