'River' in the Bible

From this wilderness and Lebanon, and unto the great river, the river Phrath, all the land of the Hittites, and unto the great Sea -- the going in of the sun -- is your border.

And Joshua saith unto all the people, 'Thus said Jehovah, God of Israel, Beyond the River have your fathers dwelt of old -- Terah father of Abraham and father of Nachor -- and they serve other gods;

and I take your father Abraham from beyond the River, and cause him to go through all the land of Canaan, and multiply his seed, and give to him Isaac.

'And now, fear ye Jehovah, and serve Him, in perfection and in truth, and turn aside the gods which your fathers served beyond the River, and in Egypt, and serve ye Jehovah;

and if wrong in your eyes to serve Jehovah -- choose for you to-day whom ye do serve; -- whether the gods whom your fathers served, which are beyond the River, or the gods of the Amorite in whose land ye are dwelling; and I and my house -- we serve Jehovah.'
