20 and he taketh the calf which they have made, and burneth 'it' with fire, and grindeth until 'it is' small, and scattereth on the face of the waters, and causeth the sons of Israel to drink.
21 And Moses saith unto Aaron, 'What hath this people done to thee, that thou hast brought in upon it a great sin?' 22 and Aaron saith, 'Let not the anger of my lord burn; thou—thou hast known the people that it 'is' in evil;

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.
