The Hiddekel (Heb: Chiddeqel; Persian: Tigra) was one of four rivers that flowed from the region of the Garden of Eden. This also known as the Tigris. It is said to have been the one that ran towards the east of Assyria (Asshur). It branched off from a mighty river that came "out of" the Garden. Most translations favor using the Tigris, based on both the Greek and Latin forms of the original.
