32:23 They said, make us Gods - It is natural to us to endeavour thus to transfer our guilt. He likewise extenuates his own share in the sin, as if he had only bid them break off their gold, intending but to make a hasty essay for the present, and childishly insinuates that when he cast the gold into the fire, it came out either by accident, or by the magic art of some of the mixt multitude (as the Jewish writers dream) in this shape. This was all Aaron had to say for himself, and he had better have said nothing, for his defence did but aggravate his offence; and yet as sin did abound, grace did much more abound.
32:21-29 Never did any wise man make a more frivolous and foolish excuse than that of Aaron. We must never be drawn into sin by any thing man can say or do to us; for men can but tempt us to sin, they cannot force us. The approach of Moses turned the dancing into trembling. They were exposed to shame by their sin. The course Moses took to roll away this reproach, was, not by concealing the sin, or putting any false colour upon it, but by punishing it. The Levites were to slay the ringleaders in this wickedness; yet none were executed but those who openly stood forth. Those are marked for ruin who persist in sin: those who in the morning were shouting and dancing, before night were dying. Such sudden changes do the judgments of the Lord sometimes make with sinners that are secure and jovial in their sin.
