2 Samuel 17:17-20

17Jonathan and Ahimaaz were waiting at En Rogel. They could not risk being seen coming into the city, so a servant girl was to go and tell them, and they were to go and tell King David.

18But a young man saw Jonathan and Ahimaaz and told Absalom. So both of them left quickly and came to the home of a man in Bahurim who had a cistern in his courtyard, and they went down into it.

19The man’s wife took a cover, spread it over the top of the cistern, and scattered some grain over it so that no one could tell it was there.

20Absalom’s servants came to the woman at her home. “Where are Ahimaaz and Jonathan?” they asked. The woman said, “They’ve crossed the stream.” The servants looked for them but did not find them. So Absalom’s servants returned to Jerusalem.
