15 Moses turned, and went down from the mountain, with the two tablets of the testimony in his hand; tablets that were written on both their sides; on the one side and on the other they were written. 16 The tablets were the work of God, and the writing was the writing of God, engraved on the tables. 17 When Joshua heard the noise of the people as they shouted, he said to Moses, “There is the noise of war in the camp.” 18 He said, “It isn’t the voice of those who shout for victory, neither is it the voice of those who cry for being overcome; but the noise of those who sing that I hear.” 19 It happened, as soon as he came near to the camp, that he saw the calf and the dancing: and Moses’ anger grew hot, and he threw the tablets out of his hands, and broke them beneath the mountain. 20 He took the calf which they had made, and burnt it with fire, ground it to powder, and scattered it on the water, and made the children of Israel drink of it.

21 Moses said to Aaron, “What did these people do to you, that you have brought a great sin on them?” 22 Aaron said, “Don’t let the anger of my lord grow hot. You know the people, that they are set on evil. 23 For they said to me, ‘Make us gods, which shall go before us; for as for this Moses, the man who brought us up out of the land of Egypt, we don’t know what has become of him.’ 24 I said to them, ‘Whoever has any gold, let them take it off:’ so they gave it to me; and I threw it into the fire, and out came this calf.” 25 When Moses saw that the people had broken loose, (for Aaron had let them loose for a derision among their enemies), 26 then Moses stood in the gate of the camp, and said, “Whoever is on Yahweh’s side, come to me!”

All the sons of Levi gathered themselves together to him. 27 He said to them, “Thus says Yahweh, the God of Israel, ‘Every man put his sword on his thigh, and go back and forth from gate to gate throughout the camp, and every man kill his brother, and every man his companion, and every man his neighbor.’” 28 The sons of Levi did according to the word of Moses: and there fell of the people that day about three thousand men. 29 Moses said, “Consecrate yourselves today to Yahweh, yes, every man against his son, and against his brother; that he may bestow on you a blessing this day.”

30 It happened on the next day, that Moses said to the people, “You have sinned a great sin. Now I will go up to Yahweh. Perhaps I shall make atonement for your sin.” 31 Moses returned to Yahweh, and said, “Oh, this people have sinned a great sin, and have made themselves gods of gold. 32 Yet now, if you will, forgive their sin—and if not, please blot me out of your book which you have written.” 33 Yahweh said to Moses, “Whoever has sinned against me, him will I blot out of my book. 34 Now 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 punish, I will punish them for their sin.” 35 Yahweh struck the people, because they made 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.
