15 Then Moses turned and went down from the mountain with the two tablets of the testimony in his hand, tablets that were written on both sides; on the front and on the back they were written. 16 The tablets were the work of God, and the writing was the writing of God, engraved on the tablets. 17 When Joshua heard the noise of the people as they shouted, he said to Moses, "There is a noise of war in the camp." 18 But he said, "It is not the sound of shouting for victory, or the sound of the cry of defeat, but the sound of singing that I hear." 19 And as soon as he came near the camp and saw the calf and the dancing, Moses' anger burned hot, and he threw the tablets out of his hands and broke them at the foot of the mountain. 20 He took the calf that they had made and burned it with fire and ground it to powder and scattered it on 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 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."

30 The next day Moses said to the people, "You have sinned a great sin. And now I will go up to the Lord; perhaps I can make atonement for your sin." 31 So Moses returned to the Lord and said, "Alas, this people has sinned a great sin. They have made for themselves gods of gold. 32 But now, if you will forgive their sin--but if not, please blot me out of your book that you have written." 33 But the Lord said to Moses, "Whoever has sinned against me, I will blot out of my book. 34 But now go, lead the people to the place about which I have spoken to you; behold, my angel shall go before you. Nevertheless, in the day when I visit, I will visit their sin upon them." 35 Then the Lord sent a plague on the people, because they made the calf, the one that Aaron made.

Commentary on Exodus 32:15-20

(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.

Commentary on Exodus 32:30-35

(Read Exodus 32:30-35)

Moses calls it a great sin. The work of ministers is to show people the greatness of their sins. The great evil of sin appears in the price of pardon. Moses pleads with God for mercy; he came not to make excuses, but to make atonement. We are not to suppose that Moses means that he would be willing to perish for ever, for the people's sake. We are to love our neighbour as ourselves, and not more than ourselves. But having that mind which was in Christ, he was willing to lay down his life in the most painful manner, if he might thereby preserve the people. Moses could not wholly turn away the wrath of God; which shows that the law of Moses was not able to reconcile men to God, and to perfect our peace with him. In Christ alone, God so pardons sin as to remember it no more. From this history we see, that no unhumbled, carnal heart, can long endure the holy precepts, the humbling truths, and the spiritual worship of God. But a god, a priest, a worship, a doctrine, and a sacrifice, suited to the carnal mind, will ever meet with abundance of worshippers. The very gospel itself may be so perverted as to suit a worldly taste. Well is it for us, that the Prophet like unto Moses, but who is beyond compare more powerful and merciful, has made atonement for our souls, and now intercedes in our behalf. Let us rejoice in his grace.
