1 Samuel 15:1-3

Samuel said to Saul, “GOD sent me to anoint you king over his people, Israel. Now, listen again to what GOD says. This is the GOD-of-the-Angel-Armies speaking: “‘I’m about to get even with Amalek for ambushing Israel when Israel came up out of Egypt. Here’s what you are to do: Go to war against Amalek. Put everything connected with Amalek under a holy ban. And no exceptions! This is to be total destruction—men and women, children and infants, cattle and sheep, camels and donkeys—the works.’”
