'River' in the Bible

From the wilderness, and this Lebanon, even to the great river, the river Euphrates, all the land of the Hittites, and to the great sea toward the going down of the sun, shall be your border.

Sihon king of the Amorites, who lived in Heshbon, and ruled from Aroer, which is on the edge of the valley of the Arnon, and the middle of the valley, and half Gilead, even to the river Jabbok, the border of the children of Ammon;

The border went up to Debir from the valley of Achor, and so northward, looking toward Gilgal, that is over against the ascent of Adummim, which is on the south side of the river. The border passed along to the waters of En Shemesh, and ended at En Rogel.

Joshua said to all the people, "Thus says Yahweh, the God of Israel, 'Your fathers lived of old time beyond the River, even Terah, the father of Abraham, and the father of Nahor: and they served other gods.

I took your father Abraham from beyond the River, and led him throughout all the land of Canaan, and multiplied his seed, and gave him Isaac.

"Now therefore fear Yahweh, and serve him in sincerity and in truth. Put away the gods which your fathers served beyond the River, in Egypt; and serve Yahweh.

If it seems evil to you to serve Yahweh, choose this day whom you will serve; whether the gods which your fathers served that were beyond the River, or the gods of the Amorites, in whose land you dwell: but as for me and my house, we will serve Yahweh."
