20 And he took the calf which they had made, and burnt it with fire, and ground it to powder, and scattered it upon the water, and made the people of Israel drink it.
21 And Moses said to Aaron, "What did this people do to you that you have brought 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.

(Read Exodus 32:15-20)
What a change it is, to come down from the mount of communion with God, to converse with a wicked world. In God we see nothing but what is pure and pleasing; in the world nothing but what is sinful and provoking. That it might appear an idol is nothing in the world, Moses ground the calf to dust. Mixing this powder with their drink, signified that the backslider in heart should be filled with his own ways.
Commentary on Exodus 32:21-29
(Read Exodus 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.
