'River' in the Bible

Resume your journey and go to the hill country of the Amorites and their neighbors in the Arabah, the hill country, the Judean foothills, the Negev and the sea coast—to the land of the Canaanites and to Lebanon as far as the Euphrates River.

But you did not go near the Ammonites’ land, all along the bank of the Jabbok River, the cities of the hill country, or any place that the Lord our God had forbidden.

and I gave to the Reubenites and Gadites the area extending from Gilead to the Arnon Valley (the middle of the valley was the border) and up to the Jabbok River, the border of the Ammonites.

Every place the sole of your foot treads will be yours. Your territory will extend from the wilderness to Lebanon and from the Euphrates River to the Mediterranean Sea.
