1 Samuel 15:10

Saul struck the Amalekites, from Havilah as you go to Shur, which is before Egypt.

He took Agag the king of the Amalekites alive, and utterly destroyed all the people with the edge of the sword.

But Saul and the people spared Agag and the best of the sheep, of the cattle, of the fat calves, of the lambs, and all that was good, and were not willing to utterly destroy them; but everything that was vile and refuse, that they destroyed utterly.

“It grieves me that I have set up Saul to be king, for he has turned back from following me, and has not performed my commandments.” Samuel was angry; and he cried to the LORD all night.

Samuel rose early to meet Saul in the morning; and Samuel was told, saying, “Saul came to Carmel, and behold, he set up a monument for himself, turned, passed on, and went down to Gilgal.”

Samuel came to Saul; and Saul said to him, “You are blessed by the LORD! I have performed the commandment of the LORD.”
