2And Joshua said to all the people, “Thus says the LORD, the God of Israel, ‘Long ago, your fathers lived beyond the Euphrates, Terah, the father of Abraham and of Nahor; and they served other gods.
Beyond the Euphrates is the land in the area of Babylon. This verse is a reference to Abram, who first lived in Ur, part of Babylon.
