1 Samuel 15:7-11 New American Bible, Revised Edition (NABRE)

7. Saul routed Amalek from Havilah to the approaches of Shur, on the frontier of Egypt.

8. He took Agag, king of Amalek, alive, but the rest of the people he destroyed by the sword, putting them under the ban.

9. He and his troops spared Agag and the best of the fat sheep and oxen, and the lambs. They refused to put under the ban anything that was worthwhile, destroying only what was worthless and of no account.

10. Then the word of the Lord came to Samuel:

11. I regret having made Saul king, for he has turned from me and has not kept my command. At this Samuel grew angry and cried out to the Lord all night.
