His name was Abiathar. 22:21 Abiathar told David that Saul had killed the priests of the Lord. 22:22 Then David said to Abiathar, “I knew that day when Doeg the Edomite was there that he would certainly tell Saul! I am guilty of all the deaths in your father’s house! 22:23 Stay with me. Don’t be afraid! Whoever seeks my life is seeking your life as well. You are secure with me.”

15:24 Then Saul said to Samuel, “I have sinned, for I have disobeyed what the Lord commanded and what you said as well. For I was afraid of the army, and I followed their wishes. 15:25 Now please forgive my sin! Go back with me so I can worship the Lord.”

15:26 Samuel said to Saul, “I will not go back with you, for you have rejected the word of the Lord, and the Lord has rejected you from being king over Israel!”

15:27 When Samuel turned to leave, Saul grabbed the edge of his robe and it tore. 15:28 Samuel said to him, “The Lord has torn the kingdom of Israel from you this day and has given it to one of your colleagues who is better than you! 15:29 The Preeminent One of Israel does not go back on his word or change his mind, for he is not a human being who changes his mind.”
