2 Samuel 17:15-16

15Hushai told Zadok and Abiathar, the priests, “Ahithophel has advised Absalom and the elders of Israel to do such and such, but I have advised them to do so and so.

16Now send a message at once and tell David, ‘Do not spend the night at the fords in the wilderness; cross over without fail, or the king and all the people with him will be swallowed up.’ ”
