'River' in the Bible

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

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

and 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; and the border passed along to the waters of En-shemesh, and the goings out thereof were at En-rogel;

And Joshua said unto all the people, Thus saith Jehovah, the God of Israel, Your fathers dwelt of old time beyond the River, even Terah, the father of Abraham, and the father of Nahor: and they served other gods.

And 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 Jehovah, and serve him in sincerity and in truth; and put away the gods which your fathers served beyond the River, and in Egypt; and serve ye Jehovah.

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