2 Samuel 17:17-20

17Jonathan and Ahimaaz were staying at En Rogel. A female servant was to go and inform them, and they were to go and tell King David, for they could not risk being seen entering the city.

18But a young man saw them and told Absalom. So the two of them left at once and went to the house of a man in Bahurim. He had a well in his courtyard, and they climbed down into it.

19His wife took a covering and spread it out over the opening of the well and scattered grain over it. No one knew anything about it.

20When Absalom’s men came to the woman at the house, they asked, “Where are Ahimaaz and Jonathan?” The woman answered them, “They crossed over the brook.” The men searched but found no one, so they returned to Jerusalem.
