2 Samuel 17:15-17

15Then Hushai said to Zadok and Abiathar the priests, “Thus and so Ahithophel advised Absalom and the elders of Israel, and thus and so I have advised.

16Now therefore, send quickly and tell David, saying, ‘Do not spend this night in the plains of the wilderness, but speedily cross over, lest the king and all the people who are with him be swallowed up.’ ”

17Now Jonathan and Ahimaaz stayed at En Rogel, for they dared not be seen coming into the city; so a female servant would come and tell them, and they would go and tell King David.
