2 Samuel 17:19-25
English Standard Version
Chapter 17
19And the woman took and spread a covering over the well 's mouth and scattered grain on it, and nothing was known of it. 20When Absalom 's servants came to the woman at the house, they said, "Where are Ahimaaz and Jonathan?" And the woman said to them, "They have gone over the brook of water." And when they had sought and could not find them, they returned to Jerusalem.
21After they had gone, the men came up out of the well, and went and told King David. They said to David, "Arise, and go quickly over the water, for thus and so has Ahithophel counseled against you."
22Then David arose, and all the people who were with him, and they crossed the Jordan. By daybreak not one was left who had not crossed the Jordan.
