1 Samuel 15:1-3

Samuel said to Saul, “The Lord sent me to anoint you king over His people Israel. Now listen and pay close attention to the words of the Lord. Thus says the LORD of hosts (armies), ‘I will punish Amalek for what he did to Israel, how he set himself against him on the way when Israel came up from Egypt. Now go and strike Amalek and completely destroy everything that they have; do not spare them, but kill both man and woman, child and infant, ox and sheep, camel and donkey.’ ”
