The Midrash indicates that Terakh and his family were not only idolators, but idol merchants as well. In our story this presents Avram with a serious conflict. While he loves his family, he does not condone their idolatry. Avram eventually gets into big trouble after he smashes all of the idols in the idol shop, and must flee Ur for his life.
