2 Samuel 17:17-19

King James Version

¹⁷ Now Jonathan and Ahimaaz stayed by Enrogel; for they might not be seen to come into the city: and a wench went and told them; and they went and told king David.

¹⁸ Nevertheless a lad saw them, and told Absalom: but they went both of them away quickly, and came to a man's house in Bahurim, which had a well in his court; whither they went down.

¹⁹ And the woman took and spread a covering over the well's mouth, and spread ground corn thereon; and the thing was not known.
