1 Samuel 15:1-5

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.’” Saul called the army together at Telaim and prepared them to go to war—two hundred companies of infantry from Israel and another ten companies from Judah. Saul marched to Amalek City and hid in the canyon.
