Rashi on Exodus 32:31/רש"י על שמות ל״ב:ל״א

1אלהי זהב GODS OF GOLD — Moses emphasized the word “gold” as some excuse for their sin: It is You who have caused them to do this, for You gave them gold in abundance and everything they wished; what else were they likely to do if not to sin? A parable: this may be compared to a king who provides his son with food and drink, attires him with beautiful garments and hangs a money-bag round his neck and then deliberately places him at the door of a house of ill-fame! What else is the son likely to do if not to sin!? (Berakhot 32a)
