2 Samuel 17:20-21

17:20 When the servants of Absalom approached the woman at her home, they asked, “Where are Ahimaaz and Jonathan?” The woman replied to them, “They crossed over the stream.” Absalom’s men searched but did not find them, so they returned to Jerusalem.

17:21 After the men had left, Ahimaaz and Jonathan climbed out of the well. Then they left and informed King David. They advised David, “Get up and cross the stream quickly, for Ahithophel has devised a plan to catch you.”
