2 Samuel 15:34

but if you return to the city, and tell Absalom, ‘I will be your servant, O king. As I have been your father’s servant in time past, so I will now be your servant; then you will defeat for me the counsel of Ahithophel.’

But 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.
