2 Samuel 15:30-37 - Hushai Offers To Serve King David
30 Now, David, was going up by the ascent of Olivet, weeping as he went up, with his head covered, himself, passing on barefoot, - and all the people who were with him, covered every man his head, and went up, weeping as they went.
31 And, unto David, it was told, saying, Ahithophel, is among the conspirators with Absolom. And David said, Turn to foolishness, I pray thee, the counsel of Ahithophel, O Yahweh.
32 And it came to pass, when David reached the summit, where he bowed himself down unto God, that lo! there met him, Hushai the Archite, his tunic rent, and earth upon his head. 33 And David said unto him, - If thou pass over with me, then shalt thou become unto me, a burden; 34 but, if, to the city, thou return, then canst thou say unto Absolom - Thy servant, I, O king, will be, as, the servant of thy father, I was formerly, so will I, now, be thy servant: thus shalt thou frustrate for me the counsel of Ahithophel. 35 And hast thou not, with thee, there Zadok and Abiathar the priests? so then it shall be, that, what thing soever thou shalt hear out of the house of the king, thou shalt tell to Zadok and to Abiathar, the priests. 36 Lo! they have there with them, their two sons, Ahimaaz for Zadok, and Jonathan for Abiathar, - so shall ye send, by their hand, unto me, everything which ye shall hear. 37 So Hushai, David's friend, went into the city, - when, Absolom, was about to enter Jerusalem.
