2 Samuel 17:17-18

17Now Jonathan and Ahimaaz stayed at En Rogel, for they dared not be seen coming into the city; so a female servant would come and tell them, and they would go and tell King David.

18Nevertheless a lad saw them, and told Absalom. But both of them went away quickly and came to a man’s house in Bahurim, who had a well in his court; and they went down into it.
