1 Samuel 15:1-3

1Then Samuel said to Saul, “I was the one the Lord sent to anoint you as king over his people Israel. Now listen to what the Lord says.

2Here is what the Lord of hosts says: ‘I carefully observed how the Amalekites opposed Israel along the way when Israel came up from Egypt.

3So 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.’”
