Shmuel Alef 15:9-11

Orthodox Jewish Bible

⁹ But Sha’ul and HaAm spared Agag, and the best of the tzon, and of the bakar, and of the fat bulls, and the fat sheep, and all that was tov, and would not utterly destroy them; but everything that was despised and worthless, that they destroyed with utter cherem destruction.

¹⁰ Then came the Devar Hashem unto Shmuel, saying,

¹¹ I greatly regret and relent and reconsider that I have set up Sha’ul to be Melech; for he is turned back from following Me, and hath not performed My Devar. And it grieved Shmuel; and he cried out unto Hashem kol halailah.
