Jordan River
The Jordan River connects the Sea of Galilee to the Dead Sea. When Abraham and Lot separated, Lot settled in the river's plains. Later, when the Israelites began to conquer the promised land, they had to first cross the Jordan River to enter the land. The river was at its flood stage, but God held back the waters so they could cross. It was also in these waters that John the Baptist baptized Jesus Christ.

The Jordan River has been the boundary between Israel and the nation of Jordan since 1967
