Dear @Persistent and @DOTS,
Reading, 1 Samuel 15:1 - 15:28, explains by not following the voice of "I AM" through Samuel, how the kingdom of Israel was torn from Saul and "I AM" hath given to a neighbour... - punishment
15:1 Samuel also said unto Saul, The "I AM" sent me to anoint thee [to be] king over His people, over Israel: now therefore hearken thou unto the words of the "I AM".
15:2 Thus saith the "I AM" Lord of hosts, I remember [that] which Amalek did to Israel, how he laid [wait] for him in the way, when he came up from Egypt.
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.
15:4 And Saul gathered the people together, and numbered them in Telaim, two hundred thousand footmen, and ten thousand men of Judah.
15:5 And Saul came to a city of Amalek, and laid wait in the valley.
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.
15:7 And Saul smote the Amalekites from Havilah [until] thou comest to Shur, that [is] over against Egypt.
15:8 And he took Agag the king of the Amalekites alive, and utterly destroyed all the people with the edge of the sword.
15:9 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.
15:10 Then came the Word of the "I AM" unto Samuel, saying,
15:11 I repent 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 "I AM" all night.
15:12 And when Samuel rose early to meet Saul in the morning, it was told Samuel, saying, Saul came to Carmel, and, behold, he set him up a place, and is gone about, and passed on, and gone down to Gilgal.
15:13 And Samuel came to Saul: and Saul said unto him, Blessed [be] thou of the "I AM": I have performed the commandment of the "I AM".
15:14 And Samuel said, What [meaneth] then this bleating of the sheep in mine ears, and the mooing of the oxen which I hear?
15:15 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 "I AM" thy God; and the rest we have utterly destroyed.
15:16 Then Samuel said unto Saul, Stay, and I will tell thee what the "I AM" hath said to me this night. And he said unto him, Say on.
15:17 And Samuel said, When thou [wast] little in thine own sight, [wast] thou not [made] the head of the tribes of Israel, and the "I AM" anointed thee king over Israel?
15:18 And the "I AM" sent thee on a journey, and said, Go and utterly destroy the sinners the Amalekites, and fight against them until they be consumed.
15:19 Wherefore then didst thou not obey the voice of the "I AM", but didst fly upon the spoil, and didst evil in the sight of the "I AM"?
15:20 And Saul said unto Samuel, Yea, I have obeyed the voice of the "I AM", and have gone the way which the "I AM" sent me, and have brought Agag the king of Amalek, and have utterly destroyed the Amalekites.
15:21 But the people took of the spoil, sheep and oxen, the chief of the things which should have been utterly destroyed, to sacrifice unto the "I AM" thy God in Gilgal.
15:22 And Samuel said, Hath the "I AM" [as great] a delight in burnt offerings and sacrifices, as in obedience to the voice of the "I AM"? Behold, to obey [is] better than sacrifice, [and] to hearken than the fat of rams.
15:23 For rebellion [is as] the sin of witchcraft, and stubbornness [is as] iniquity and idolatry. Because thou hast rejected the word of the "I AM", He hath also rejected thee from [being] king.
15:24 And Saul said unto Samuel, I have sinned: for I have transgressed the commandment of the "I AM", and thy words: because I feared the people, and obeyed their voice.
15:25 Now therefore, I pray thee, pardon my sin, and turn again with me, that I may worship the "I AM".
15:26 And Samuel said unto Saul, I will not return with thee: for thou hast rejected the word of the "I AM", and the "I AM" hath rejected thee from being king over Israel.
15:27 And as Samuel turned about to go away, he laid hold upon the skirt of his mantle, and it tore.
15:28 And Samuel said unto him, The "I AM" hath torn the kingdom of Israel from thee this day, and hath given it to a neighbour of thine, [that is] better than thou.
