2 Samuel 17:21-22

21After the men had gone, Ahimaaz and Jonathan climbed out of the well. Then they took the message to David. They said to him, ‘You must go across the river immediately. Ahithophel has told Absalom how he can catch you here.’

22So David and all the people who were with him went across the Jordan River. When dawn came, they had all gone across to the other side.
