2 Samuel 17:15-17

15Then 1Hushai said to Zadok and to Abiathar the priests, “2This is what Ahithophel advised Absalom and the elders of Israel to do, and 3this is what I have advised.

16Now then, send a messenger quickly and tell David, saying, ‘4Do not spend the night at the river crossing places of the wilderness, but by all means cross over, or else the king and all the people who are with him will be 5destroyed.’”

176Now Jonathan and Ahimaaz were staying at 7En-rogel, and a female servant would go and inform them, and they would go and inform King David, for they could not allow themselves to be seen entering the city.
