15 And Moses turned and went down from the mountain, and the two tablets of the Testimony were in his hand. The tablets were written on both sides; on the one side and on the other they were written. 16 Now the tablets were the work of God, and the writing was the writing of God engraved on the tablets. 17 And 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 noise of the shout of victory, Nor the noise of the cry of defeat, But the sound of singing I hear." 19 So it was, as soon as he came near the camp, that he saw the calf and the dancing. So Moses' anger became hot, and he cast the tablets out of his hands and broke them at the foot of the mountain. 20 Then he took the calf which they had made, burned it in the fire, and ground it to powder; and he scattered it on the water and made the children of Israel drink it.

21 And Moses said to Aaron, "What did this people do to you that you have brought so great a sin upon them?" 22 So Aaron said, "Do not let the anger of my lord become hot. You know the people, that they are set on evil. 23 For they said to me, 'Make us gods that shall go before us; as for this Moses, the man who brought us out of the land of Egypt, we do not know what has become of him.' 24 And I said to them, 'Whoever has any gold, let them break it off.' So they gave it to me, and I cast it into the fire, and this calf came out." 25 Now when Moses saw that the people were unrestrained (for Aaron had not restrained them, to their shame among their enemies), 26 then Moses stood in the entrance of the camp, and said, "Whoever is on the Lord's side--come to me." And all the sons of Levi gathered themselves together to him. 27 And he said to them, "Thus says the Lord God of Israel: 'Let every man put his sword on his side, and go in and out from entrance to entrance throughout the camp, and let every man kill his brother, every man his companion, and every man his neighbor.' " 28 So the sons of Levi did according to the word of Moses. And about three thousand men of the people fell that day. 29 Then Moses said, "Consecrate yourselves today to the Lord, that He may bestow on you a blessing this day, for every man has opposed his son and his brother."

30 Now it came to pass on the next day that Moses said to the people, "You have committed a great sin. So now I will go up to the Lord; perhaps I can make atonement for your sin." 31 Then Moses returned to the Lord and said, "Oh, these people have committed a great sin, and have made for themselves a god of gold! 32 Yet now, if You will forgive their sin--but if not, I pray, blot me out of Your book which You have written." 33 And the Lord said to Moses, "Whoever has sinned against Me, I will blot him out of My book. 34 Now therefore, go, lead the people to the place of which I have spoken to you. Behold, My Angel shall go before you. Nevertheless, in the day when I visit for punishment, I will visit punishment upon them for their sin." 35 So the Lord plagued the people because of what they did with the calf which 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.
