4 Bible Verses about Apostasy Of Saul

But Samuel said to Saul, "I will not return with you, for you have rejected the word of Yahweh, and he has rejected you from being king over Israel!" As Samuel turned around to go, he caught hold of the hem of his robe, and it tore. Then Samuel said to him, "Yahweh has torn the kingdom of Israel from you today and has given it to your neighbor {who is better than you}.read more.
Moreover, the Glory of Israel will not break faith and will not regret, for he [is] not a human that he should regret."

{Now Saul was threatened by the presence of David} because Yahweh was with him, but had departed from Saul.

Then Samuel said to Saul, "Why have you disturbed me by bringing me up?" And Saul said, "{I am in distress}! For [the] Philistines [are about] to make war against me, but God has turned away from me, and he does not answer me any more, not {by the prophets} or by the dreams. So I called to you to let me know what I should do."

Because you {did not obey} Yahweh and did not carry out the fierce anger of his {wrath} against Amalek, therefore Yahweh has done this thing to you today.
