1 Samuel 15:9-11 Darby Translation (DARBY)
9 And Saul and the people spared Agag, and the best of the sheep and oxen, and beasts of the second bearing, and the lambs, and all that was good, and would not devote them to destruction; but everything that was mean and weak, that they destroyed utterly.
10 And the word of Jehovah came to Samuel, saying,
11 It repenteth me that I have set up Saul to be king; for he is turned away from following me, and hath not fulfilled my words. And Samuel was much grieved; and he cried to Jehovah all night.
