At the beginning, our ancestors were idol worshipers; but now, the Omnipresent has brought us close to His worship; as it is stated (Joshua 24:2-4), "Yehoshua said to the whole people, so said Hashem, G-d of Israel, Across the river did your ancestors dwell from always, Terach the father of Avraham and the father of Nachor, and they worshiped other gods. And I took your father, Avraham, from across the river, and I made him walk in all the land of Canaan, and I increased his seed and I gave him Yitzchak. And I gave to Yitzchak, Yaakov and Esav; I gave to Esav, Mount Seir [in order that he] inherit it; whereas Yaakov and his sons went down to Egypt.'"
