2 Samuele 3:8

Then was Abner very wroth for the words of Ishbosheth, and said, Am I a dog's head, which against Judah do shew kindness this day unto the house of Saul thy father, to his brethren, and to his friends, and have not delivered thee into the hand of David, that thou chargest me to day with a fault concerning this woman? Am I a dog's head - Dost thou treat a man with indignity who has been the only prop of thy tottering kingdom, and the only person who could make head against the house of David?
