1 Samuel 15:17-24

17 Samuel said, "Though you were little in your own sight, weren't you made the head of the tribes of Israel? Yahweh anointed you king over Israel;  18 and Yahweh sent you on a journey, and said, 'Go, and utterly destroy the sinners the Amalekites, and fight against them until they are consumed.'  19 Why then didn't you obey the voice of Yahweh, but flew on the spoil, and did that which was evil in the sight of Yahweh?"  20 Saul said to Samuel, Yes, I have obeyed the voice of Yahweh, and have gone the way which Yahweh sent me, and have brought Agag the king of Amalek, and have utterly destroyed the Amalekites.  21 But the people took of the spoil, sheep and oxen, the chief of the devoted things, to sacrifice to Yahweh your God in Gilgal.  22 Samuel said, Has Yahweh as great delight in burnt offerings and sacrifices, as in obeying the voice of Yahweh? Behold, to obey is better than sacrifice, and to listen than the fat of rams.  23 For rebellion is as the sin of witchcraft, and stubbornness is as idolatry and teraphim. Because you have rejected the word of Yahweh, he has also rejected you from being king.  24 Saul said to Samuel, I have sinned; for I have transgressed the commandment of Yahweh, and your words, because I feared the people, and obeyed their voice.
