Musar do Powtórzonego Prawa 10:19

The warning to remove all vestiges of idol-worship is part of the overall directive of סור מרע, "stay away from evil." The wording of the prohibition not to covet appurtenances of former idolatry is a reminder that once one covets something one is liable to take steps to acquire it. When the Torah says: לא תביא תועבה אל ביתך, this is not the same as saying: לא תביא תועבה לביתך. The wording of the Torah teaches that the transport of the item is culpable, even before its arrival in your house. Following examples of distancing oneself from evil, the Torah continues to urge us ועשה טוב, to actively engage in doing good. An example of the latter is the commandment to love the stranger, i.e. the one who has forsaken the path of idol-worship. These converts are so beloved by G–d that He associates one's loving them with loving G–d Himself. This is why the Torah uses the word אהבה both for the feelings we are to harbor towards G–d as well as for the feelings we are to harbor and display towards the stranger who has embraced Judaism.
