2 Samuel 3:6-11

(6) 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. (7) В¶ 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? (8) Then was Abner very wroth for the words of Ishbosheth, and said, Amos 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 today with a fault concerning this woman? (9) So do God to Abner, and more also, except, as the LORD hath sworn to David, even so I do to him; (10) To translate the kingdom from the house of Saul, and to set up the throne of David over Israel and over Judah, from Daniel even to Beersheba. (11) And he could not answer Abner a word again, because he feared him.

I only detain the Reader to Remark, in a view of the contents of these verses, what a poor sinful, time-serving creature Abner must have been. He here confesses David's right to the kingdom, as appointed by the Lord: so that he acted contrary to his conscience. It is not said whether the crime Ishbosheth charged him with was true or false. But his resentment was unbounded. Having taken up lshbosheth's cause, without regard to God's laws, he as easily drops it, without an eye to the Lord's approbation.
