2 Samuel (Author Compiled by Isaiah from records of Samuel, David, Nathan, and Gad.)
15:34But if thou return to the city, and say unto Absalom, I will be thy servant, O king; as I have been thy father's servant hitherto, so will I now also be thy servant: then mayest thou for me defeat the counsel of Ahithophel.
