'Ancestors' in the Bible

Joshua said to all the people, “This is what the Lord, the God of Israel, says: ‘Long ago your ancestors, including Terah, the father of Abraham and Nahor, lived beyond the Euphrates River and worshiped other gods.

“Therefore, fear the Lord and worship Him in sincerity and truth. Get rid of the gods your fathers worshiped beyond the Euphrates River and in Egypt, and worship Yahweh.
