2 Samuel 17:17-20

17Now Jonathan and Ahimaaz were staying at En-rogel, and a maidservant used to go and pass information along to them. Then they would go and inform King David for they could not be seen entering the city.

18But a lad did see them and informed Absalom. So the two of them left quickly and arrived at the house of a man in Bahurim. He had a well in his courtyard; so they went down into it.

19Then the woman took the cover and spread it over the well’s mouth and scattered grain on top of it so that nothing was noticeable.

20When Absalom’s servants came to the woman at the house and said, “Where are Ahimaaz and Jonathan?” the woman said to them, “They crossed over the brook of water.” When they had searched and could not find them, they returned to Jerusalem.
