2 Samuel 3:1-7

Now there was long war between the house of Saul and the house of David: and David waxed stronger and stronger, but the house of Saul waxed weaker and weaker. And unto David were sons born in Hebron: and his first-born was Amnon, of Ahinoam the Jezreelitess; and his second, Chileab, of Abigail the wife of Nabal the Carmelite; and the third, Absalom the son of Maacah the daughter of Talmai king of Geshur; and the fourth, Adonijah the son of Haggith; and the fifth, Shephatiah the son of Abital; and the sixth, Ithream, of Eglah, David’s wife. These were born to David in Hebron. And it came to pass, while there was war between the house of Saul and the house of David, that Abner made himself strong in the house of Saul. Now Saul had a concubine, whose name was Rizpah, the daughter of Aiah: and Ish-bosheth said to Abner, Wherefore hast thou gone in unto my father’s concubine?
