2 Samuel 17:17-20

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.

18But this time a young man did see them. He told Absalom where they were. So they quickly left En Rogel and they went to a man's house in Bahurim. He had a well in his yard and they climbed down into it.

19His wife took a lid and she put it over the top of the well. Then she put some grain on it. Nobody knew that the men were hiding there.

20Absalom's men came to the house. They asked the woman, ‘Where are Ahimaaz and Jonathan?’ The woman answered, ‘They went across the stream.’ Absalom's men looked everywhere for them, but they did not find them. So they returned to Jerusalem.
