1 Samuel 15:1–3
1 And Samuel said to Saul, “The Lord sent me to anoint you king over his people Israel; now therefore hearken to the words of the Lord. 2 Thus says the Lord of hosts, ‘I will punish what Amalek did to Israel in opposing them on the way, when they came up out of Egypt. 3 Now go and smite Amalek, and utterly destroy all that they have; do not spare them, but kill both man and woman, infant and suckling, ox and sheep, camel and ass.’ ”
