2 Samuel 17:15-17

15Then Hushai told the priests Zadok and Abiathar, “Ahithophel advised Absalom and the leaders of Israel to do one thing, but I advised them to do something else.

16Now send messengers quickly to tell David, ‘Don’t rest tonight in the river crossings in the desert, but make sure you cross ⌞the river⌟, or Your Majesty and all the troops with him will be wiped out.’ ”

17Jonathan and Ahimaaz were waiting at En Rogel. They could not risk being seen coming into the city, so a servant girl was to go and tell them, and they were to go and tell King David.
