2 Samuel 3:4

Now there was a long war between Saul’s house and David’s house. David grew stronger and stronger, but Saul’s house grew weaker and weaker.

Sons were born to David in Hebron. His firstborn 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 sixth, Ithream, of Eglah, David’s wife. These were born to David in Hebron.

While there was war between Saul’s house and David’s house, Abner made himself strong in Saul’s house.

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