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