2 Samuel 3:5 (KJV)

Now there was long war between the house of Saul and the house of David: but David waxed stronger and stronger, and the house of Saul waxed weaker and weaker.

And unto David were sons born in Hebron: and 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 fourth, Adonijah the son of Haggith; and the fifth, Shephatiah the son of Abital;

And 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.

And 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?

Then 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?

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

To 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.
