הלכה אויף יהושע 24:2

From the beginning, our ancestors were idol worshipers. And now, the Place [of all] has brought us close to His worship, as it is stated (Joshua 24:2-4), "Joshua said to the whole people, so said the Lord, God of Israel, 'Over the river did your ancestors dwell from always, Terach the father of Abraham and the father of Nachor, and they worshiped other gods. And I took your father, Abraham, from over the river and I made him walk in all the land of Canaan and I increased his seed and I gave him Isaac. And I gave to Isaac, Jacob and Esau; and I gave to Esau, Mount Seir [in order that he] inherit it; and Jacob and his sons went down to Egypt.'"
