15 Then Moses turned and went down the mountain. He held in his hands the two stone tablets inscribed with the terms of the covenant. They were inscribed on both sides, front and back. 16 These tablets were God's work; the words on them were written by God himself. 17 When Joshua heard the boisterous noise of the people shouting below them, he exclaimed to Moses, "It sounds like war in the camp!" 18 But Moses replied, "No, it's not a shout of victory nor the wailing of defeat. I hear the sound of a celebration." 19 When they came near the camp, Moses saw the calf and the dancing, and he burned with anger. He threw the stone tablets to the ground, smashing them at the foot of the mountain. 20 He took the calf they had made and burned it. Then he ground it into powder, threw it into the water, and forced the people to drink it.

21 Finally, he turned to Aaron and demanded, "What did these people do to you to make you bring such terrible sin upon them?" 22 "Don't get so upset, my lord," Aaron replied. "You yourself know how evil these people are. 23 They said to me, 'Make us gods who will lead us. We don't know what happened to this fellow Moses, who brought us here from the land of Egypt.' 24 So I told them, 'Whoever has gold jewelry, take it off.' When they brought it to me, I simply threw it into the fire-and out came this calf!" 25 Moses saw that Aaron had let the people get completely out of control, much to the amusement of their enemies. 26 So he stood at the entrance to the camp and shouted, "All of you who are on the Lord 's side, come here and join me." And all the Levites gathered around him. 27 Moses told them, "This is what the Lord, the God of Israel, says: Each of you, take your swords and go back and forth from one end of the camp to the other. Kill everyone-even your brothers, friends, and neighbors." 28 The Levites obeyed Moses' command, and about 3,000 people died that day. 29 Then Moses told the Levites, "Today you have ordained yourselves for the service of the Lord, for you obeyed him even though it meant killing your own sons and brothers. Today you have earned a blessing."

30 The next day Moses said to the people, "You have committed a terrible sin, but I will go back up to the Lord on the mountain. Perhaps I will be able to obtain forgiveness for your sin." 31 So Moses returned to the Lord and said, "Oh, what a terrible sin these people have committed. They have made gods of gold for themselves. 32 But now, if you will only forgive their sin-but if not, erase my name from the record you have written!" 33 But the Lord replied to Moses, "No, I will erase the name of everyone who has sinned against me. 34 Now go, lead the people to the place I told you about. Look! My angel will lead the way before you. And when I come to call the people to account, I will certainly hold them responsible for their sins." 35 Then the Lord sent a great plague upon the people because they had worshiped the calf 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.
