'River' in the Bible

When Samlah died, Shaul from Rehoboth on the Euphrates River ruled in his place.

They also settled in the east as far as the edge of the desert that extends to the Euphrates River, because their herds had increased in the land of Gilead.

So the God of Israel put it into the mind of Pul (that is, Tiglath-pileser) king of Assyria to take the Reubenites, Gadites, and half the tribe of Manasseh into exile. He took them to Halah, Habor, Hara, and Gozan’s river, where they are until today.

David also defeated King Hadadezer of Zobah at Hamath when he went to establish his control at the Euphrates River.
