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. (15:34)

And [hast thou] not there with thee Zadok and Abiathar the priests? therefore it shall be, [that] what thing soever thou shalt hear out of the king's house, thou shalt tell [it] to Zadok and Abiathar the priests. (15:35)

Behold, [they have] there with them their two sons, Ahimaaz Zadok's [son], and Jonathan Abiathar's [son]; and by them ye shall send unto me every thing that ye can hear. (15:36)

So Hushai David's friend came into the city, and Absalom came into Jerusalem. (15:37)
