1 Samuel 15:21-23
21 But the people took some of the spoil, sheep and oxen, the best of the things [that were] to be totally destroyed, to sacrifice to the Lord your God at Gilgal.” 22 Samuel said,
“Has the Lord as great a delight in burnt offerings and sacrifices
As in obedience to the voice of the Lord?
Behold, to obey is better than sacrifice,
And to heed [is better] than the fat of rams.
“For rebellion is as [serious as] the sin of divination (fortune-telling),
And disobedience is as [serious as] false religion and idolatry.
Because you have rejected the word of the Lord,
He also has rejected [a]you as king.”
- 1 Samuel 15:23 The passage does not say that God rejected Saul, the man, but rejected his being king of Israel.
