2 Samuel 3:8

6And it came to pass, while there was war between the house of Saul and the house of David, that Abner made himself strong for the house of Saul.

7And Saul had a concubine, whose name was Rizpah, the daughter of Aiah: and Ishbosheth said to Abner, Wherefore hast thou gone in unto my father’s concubine?

8Then 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?

9So do God to Abner, and more also, except, as the LORD hath sworn to David, even so I do to him;

10To translate the kingdom from the house of Saul, and to set up the throne of David over Israel and over Judah, from Dan even to Beersheba.
