2 Samuel 17:17-20

17Now Jonathan and Ahimaaz were staying in En Rogel. A female servant would go and inform them, and they would then go and inform King David. It was not advisable for them to be seen going into the city.

18But a young man saw them on one occasion and informed Absalom. So the two of them quickly departed and went to the house of a man in Bahurim. There was a well in his courtyard, and they got down in it.

19His wife then took the covering and spread it over the top of the well and scattered some grain over it. No one was aware of what she had done.

20When the servants of Absalom approached the woman at her home, they asked, “Where are Ahimaaz and Jonathan?” The woman replied to them, “They crossed over the stream.” Absalom’s men searched but did not find them, so they returned to Jerusalem.
