2 Samuel 17:15-16

15 Hushai 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.

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