'River' in the Bible

Now Solomon reigned over all the kingdoms from the [Euphrates] River to the land of the Philistines and to the border of Egypt; they brought tribute (money) and served Solomon all the days of his life.

For he was ruling over everything west of the [Euphrates] River, from Tiphsah to Gaza, over all the kings west of the [Euphrates] River; and he had peace on all sides around him.

“The Lord will strike Israel, as a reed is shaken in the water; and He will uproot Israel from this good land which He gave to their fathers, and He will scatter them beyond the [Euphrates] River, because they have made their Asherim, provoking the Lord to anger.
