2 Samuel 3:6-10

Now it happened that while there was war between the house of Saul and the house of David, Abner was strengthening himself in the house of Saul.

And Saul had a concubine whose name was Rizpah, the daughter of Aiah; and Ish-bosheth said to Abner, “Why have you gone in to my father’s concubine?”

Then Abner became very angry over Ish-bosheth’s question and said, “Am I a dog’s head that belongs to Judah? Today I show kindness to the house of Saul your father, to his brothers and to his friends, and have not let you fall into the hands of David; yet today you call me to account for wrongdoing with that woman?

May God do so to me, and more so, if as the Lord has sworn to David, I do not accomplish this for him:

to transfer the kingdom from the house of Saul, and to establish the throne of David over Israel and over Judah, from Dan even to Beersheba!”
