Shmuel Alef 15:29-31

Orthodox Jewish Bible

²⁹ And also the Netzach Yisroel (Eternal One of Israel) will not lie nor relent: for He is not an adam, that He should change His mind.

³⁰ Then he said, Chatati (I have sinned): yet honor me now, before the Ziknei Ami, and before Yisroel, and turn back with me, that I may worship Hashem Eloheicha.

³¹ So Shmuel turned back after Sha’ul; and Sha’ul worshiped Hashem.
