2 Samuel 17:15-17

15Then Hushai went to the priests Zadok and Abiathar. He said to them, ‘This was Ahithophel's advice to Absalom and Israel's leaders. But this was my advice.

16So now quickly send a report to David. Warn him that he must not stay tonight at the place in the desert where the road crosses the river. Instead, he must cross the Jordan River immediately, together with all the people who are with him. If not, Absalom and his army may catch them all and destroy them.’

17Jonathan and Ahimaaz were staying at En Rogel. They did not go into the city because they did not want anyone to see them there. So a female servant would take messages to them. Then they would take the messages to King David.
