The term 'Biblical River' refers to two rivers mentioned in the Bible: the Jordan and the Tigris. The Jordan is a river in Southwest Asia that flows from north to south through the Sea of Galilee and the Dead Sea. It is also known as the River of Israel. The Tigris is a river in Western Asia that flows from east to west through Iraq and Syria. It is one of the two rivers that form the Shatt al-Arab waterway, which empties into the Persian Gulf.
