1 Samuel 15:9-11

Young's Literal Translation

⁹ and Saul hath pity -- also the people -- on Agag, and on the best of the flock, and of the herd, and of the seconds, and on the lambs, and on all that [is] good, and have not been willing to devote them; and all the work, despised and wasted -- it they devoted.

¹⁰ And the word of Jehovah is unto Samuel, saying,

¹¹ `I have repented that I caused Saul to reign for king, for he hath turned back from after Me, and My words he hath not performed;' and it is displeasing to Samuel, and he crieth unto Jehovah all the night.
