2Sam 3:6-11

6While there was war between the house of Saul and the house of David, Abner was making himself strong in the house of Saul.7Now Saul had a concubine whose name was Rizpah daughter of Aiah. And Ishbaal said to Abner, “Why have you gone in to my father's concubine?”8The words of Ishbaal made Abner very angry; he said, “Am I a dog's head for Judah? Today I keep showing loyalty to the house of your father Saul, to his brothers, and to his friends, and have not given you into the hand of David; and yet you charge me now with a crime concerning this woman.9So may God do to Abner and so may he add to it! For just what the Lord has sworn to David, that will I accomplish for him,10to transfer the kingdom from the house of Saul, and set up the throne of David over Israel and over Judah, from Dan to Beer-sheba.”11And Ishbaal could not answer Abner another word, because he feared him.
