21 And Moses said to Aaron, "What did this people do to you that you have brought such a great sin upon them?" 22 And Aaron said, "Let not the anger of my lord burn hot. You know the people, that they are set on evil. 23 For they said to me, 'Make us gods who shall go before us. As for this Moses, the man who brought us up out of the land of Egypt, we do not know what has become of him.' 24 So I said to them, 'Let any who have gold take it off.' So they gave it to me, and I threw it into the fire, and out came this calf." 25 And when Moses saw that the people had broken loose (for Aaron had let them break loose, to the derision of their enemies), 26 then Moses stood in the gate of the camp and said, "Who is on the Lord's side? Come to me." And all the sons of Levi gathered around him. 27 And he said to them, "Thus says the Lord God of Israel, 'Put your sword on your side each of you, and go to and fro from gate to gate throughout the camp, and each of you kill his brother and his companion and his neighbor.'" 28 And the sons of Levi did according to the word of Moses. And that day about three thousand men of the people fell. 29 And Moses said, "Today you have been ordained for the service of the Lord, each one at the cost of his son and of his brother, so that he might bestow a blessing upon you this day."

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.
