'Beyond the River' in the Bible

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.
