I Samuel Chapter 15

15:3
Now go and smite Amalek, and utterly destroy all that they have, and spare them not; but slay both man and woman, infant and suckling, ox and sheep, camel and ass.

15:6
And Saul said unto the Kenites, Go, depart, get you down from among the Amalekites, lest I destroy you with them: for ye showed kindness to all the children of Israel, when they came up out of Egypt. So the Kenites departed from among the Amalekites.

15:8-11
And 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, and of the oxen, and of the fatlings, and the lambs, and all that was good, and would not utterly destroy them: but every thing that was vile and refuse, that they destroyed utterly.
Then came the word of the Lord unto Samuel, saying,
It repenteth me that I have set up Saul to be king: for he is turned back from following me, and hath not performed my commandments. And it grieved Samuel; and he cried unto the Lord all night.

15:13-17
And Samuel came to Saul: and Saul said unto him, Blessed be thou of the Lord: I have performed the commandment of the Lord.
And Samuel said, What meaneth then this bleating of the sheep in mine ears, and the lowing of oxen which I hear?
And Saul said, They have brought them from the Amalekites: for the people spared the best of the sheep and of the oxen, to sacrifice unto the Lord thy God; and the rest we have utterly destroyed.
Then Samuel said unto Saul, Stay, and I will tell thee what the Lord hath said to me this night. And he said unto him, Say on.
And Samuel said, When thou wast little in thine own sight, wast thou not made the head of the tribes of Israel, and the Lord anointed thee king over Israel?

15:22-29
And Samuel said, Hath the Lord as great delight in burnt offerings and sacrifices, as in obeying the voice of the Lord? Behold, to obey is better than sacrifice, and to hearken than the fat of rams.
For rebellion is as the sin of witchcraft, and stubbornness is as iniquity and idolatry. Because thou hast rejected the word of the Lord, he hath also rejected thee from being king.
And Saul said unto Samuel, I have sinned: for I have transgresed the commandment of the Lord, and thy words: because I feared the people, and obeyed their voice.
Now therefore, I pray thee, pardon my sin, and turn again with me, that I may worship the Lord.
And Samuel said unto Saul, I will not return with thee: for thou hast rejected the word of the Lord, and the Lord hath rejected thee from being king over Israel.
And as Samuel turned about to go away, he laid hold upon the skirt of his mantle, and it rent.
And Samuel said unto him, The Lord hath rent the kingdom of Israel from thee this day, and hath given it to a neighbour of thine, that is better than thou.
And also the Strength of Israel will not lie nor repent: for he is not a man. that he should repent.

15:32-35
Then said Samuel, Bring ye hither to me Agag the king oof the Amalekites. And Agag came unto him delicately. And Agag said, Surely the bitterness of death is past.
And Samuel said, As thy sword hath made women childless, so shall thy mother be childless among women. And Samuel hewed Agag in pieces before the Lord in Gilgal.
Then Samuel went to Ramah; and Saul went up to his house to Gibeah of Saul.
And Samuel came no more to see Saul until the day of his death: nevertheless Samuel mourned for Saul: and the Lord repented that he had made Saul king over Israel.
