2 Samuel 17:14-18
English Standard Version
15Then Hushai said to Zadok and Abiathar the priests, "Thus and so did Ahithophel counsel Absalom and the elders of Israel, and thus and so have I counseled.
16Now therefore send quickly and tell David, ‘Do not stay tonight at the fords of the wilderness, but by all means pass over, lest the king and all the people who are with him be swallowed up.’"
17Now Jonathan and Ahimaaz were waiting at En-rogel. A female servant was to go and tell them, and they were to go and tell King David, for they were not to be seen entering the city.
18But a young man saw them and told Absalom. So both of them went away quickly and came to the house of a man at Bahurim, who had a well in his courtyard. And they went down into it.
