'Beyond the River' in the Bible

Then said Joshua unto all the people - Thus, saith Yahweh, God of Israel, Beyond the River, dwelt your fathers from age-past times, unto Terah, father of Abraham, and father of Nahor, - and they served other gods.

So I took your father, Abraham, from beyond the River, and led him through all the land of Canaan, - and multiplied his seed, and gave unto him, Isaac;

Now, therefore, revere ye Yahweh, 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 Yahweh.

But, if it be, a vexation, in your eyes, to serve Yahweh, choose ye for yourselves, to-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 are dwelling, - but, I and my house, will serve Yahweh.
