Exodus 32:
1 When the people saw that Moses was so long in coming down from the mountain, they gathered around Aaron and said, "Come, make us gods who will go before us. As for this fellow Moses who brought us up out of Egypt, we don't know what has happened to him."
7 Then the LORD said to Moses, "Go down, because your people, whom you brought up out of Egypt, have become corrupt. 8 They have been quick to turn away from what I commanded them and have made themselves an idol cast in the shape of a calf. They have bowed down to it and sacrificed to it and have said, 'These are your gods, O Israel, who brought you up out of Egypt.'
Exodus 32:15 Moses turned and went down the mountain with the two tablets of the Testimony in his hands. They were inscribed on both sides, front and back. 16 The tablets were the work of God; the writing was the writing of God, engraved on the tablets.
Exodus 32:19 When Moses approached the camp and saw the calf and the dancing, his anger burned and he threw the tablets out of his hands, breaking them to pieces at the foot of the mountain. 20 And he took the calf they had made and burned it in the fire; then he ground it to powder, scattered it on the water and made the Israelites drink it.
Exodus 32:
25 Moses saw that the people were running wild and that Aaron had let them get out of control and so become a laughingstock to their enemies. 26 So he stood at the entrance to the camp and said, "Whoever is for the LORD, come to me." And all the Levites rallied to him.
27 Then he said to them, "This is what the LORD, the God of Israel, says: 'Each man strap a sword to his side. Go back and forth through the camp from one end to the other, each killing his brother and friend and neighbor.' " 28 The Levites did as Moses commanded, and that day about three thousand of the people died. 29 Then Moses said, "You have been set apart to the LORD today, for you were against your own sons and brothers, and he has blessed you this day."
30 The next day Moses said to the people, "You have committed a great sin. But now I will go up to the LORD; perhaps I can make atonement for your sin."
31 So Moses went back to the LORD and said, "Oh, what a great sin these people have committed! They have made themselves gods of gold. 32 But now, please forgive their sin—but if not, then blot me out of the book you have written."
