2 Samuel 3:8

Then was Abner very wroth for the words of Ishbosheth, for he seems to have been self-willed and presumptuous in his conduct toward the weak man whom he had made king, and said, Am I a dog's head, a low, contemptible person, which against Judah, who sides with Judah? (I) do show kindness this day unto the house of Saul, thy father, to his brethren, and to his friends, and have not delivered thee in to the hand of David, that thou chargest me today with a fault concerning this woman? Ishbosheth owed position, kingdom, everything to Abner, who seems to have been on his side merely out of loyalty for Saul; but there was no personal bond between them, and Abner regarded the charge flung into his face as an insult.
