2 Samuel 15:32-34

And it came to pass, that {when} David was come to the top {of the mount}, where he worshipped God, behold, Hushai the Archite came to meet him with his coat rent, and earth upon his head: Unto whom David said, If thou passest on with me, then thou shalt be a burden unto me: 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.
