So shall we come on him in some place where he shall be found, and we will light on him as the dew falls on the ground; and of him and of all the men who are with him we will not leave so much as one.

Then David arose, and all the people who were with him, and they passed over the Jordan. By the morning light there lacked not one of them who had not gone over the Jordan.
