15 Moses turned around and came down from the mountain, carrying the two tablets of The Testimony. The tablets were written on both sides, front and back. 16 God made the tablets and God wrote the tablets - engraved them. 17 When Joshua heard the sound of the people shouting noisily, he said to Moses, "That's the sound of war in the camp!" 18 But Moses said, Those aren't songs of victory, And those aren't songs of defeat, I hear songs of people throwing a party. 19 And that's what it was. When Moses came near to the camp and saw the calf and the people dancing, his anger flared. He threw down the tablets and smashed them to pieces at the foot of the mountain. 20 He took the calf that they had made, melted it down with fire, pulverized it to powder, then scattered it on the water and made the Israelites drink it.

21 Moses said to Aaron, "What on Earth did these people ever do to you that you involved them in this huge sin?" 22 Aaron said, "Master, don't be angry. You know this people and how set on evil they are. 23 They said to me, 'Make us gods who will lead us. This Moses, the man who brought us out of Egypt, we don't know what's happened to him.' 24 "So I said, 'Who has gold?' And they took off their jewelry and gave it to me. I threw it in the fire and out came this calf." 25 Moses saw that the people were simply running wild - Aaron had let them run wild, disgracing themselves before their enemies. 26 He took up a position at the entrance to the camp and said, "Whoever is on God's side, join me!" All the Levites stepped up. 27 He then told them, "God's orders, the God of Israel: 'Strap on your swords and go to work. Crisscross the camp from one end to the other: Kill brother, friend, neighbor.'" 28 The Levites carried out Moses' orders. Three thousand of the people were killed that day. 29 Moses said, "You confirmed your ordination today - and at great cost, even killing your sons and brothers! And God has blessed you."

30 The next day Moses addressed the people: "You have sinned an enormous sin! But I am going to go up to God; maybe I'll be able to clear you of your sin." 31 Moses went back to God and said, "This is terrible. This people has sinned - it's an enormous sin! They made gods of gold for themselves. 32 And now, if you will only forgive their sin. . . . But if not, erase me out of the book you've written." 33 God said to Moses, "I'll only erase from my book those who sin against me. 34 For right now, you go and lead the people to where I told you. Look, my Angel is going ahead of you. On the day, though, when I settle accounts, their sins will certainly be part of the settlement." 35 God sent a plague on the people because of the calf they and Aaron had 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.
