1 Samuel 15:9-11

Complete Jewish Bible

⁹ However, Sha’ul and the people spared Agag, along with the best of the sheep and cattle, and even the second best, also the lambs, and everything that was good — they weren’t inclined to destroy these things. But everything that was worthless or weak they completely destroyed.

¹⁰ Then the word of Adonai came to Sh’mu’el: ¹¹ “I regret setting up Sha’ul as king, because he has turned back from following me and hasn’t obeyed my orders.” This made Sh’mu’el very sad, so that he cried to Adonai all night.
