Exodus 32:18-32

But Moses replied: It’s not the sound of a victory cry and not the sound of a cry of defeat; I hear the sound of singing! As he approached the camp and saw the calf and the dancing, Moses became enraged and threw the tablets out of his hands, smashing them at the base of the mountain. Then he took the calf they had made, burned it up, and ground it to powder. He scattered the powder over the surface of the water and forced the Israelites to drink the water. Then Moses asked Aaron, “What did these people do to you that you have led them into such a grave sin? ” “Don’t be enraged, my lord,” Aaron replied. “You yourself know that the people are intent on evil. They said to me, ‘Make us a god who will go before us because this Moses, the man who brought us up from the land of Egypt — we don’t know what has happened to him! ’ So I said to them, ‘Whoever has gold, take it off,’ and they gave it to me. When I threw it into the fire, out came this calf! ” Moses saw that the people were out of control, for Aaron had let them get out of control, resulting in weakness before their enemies. And Moses stood at the camp’s entrance and said, “Whoever is for the LORD, come to me.” And all the Levites gathered around him. He told them, “This is what the LORD, the God of Israel, says, ‘Every man fasten his sword to his side; go back and forth through the camp from entrance to entrance, and each of you kill his brother, his friend, and his neighbor.’ ” The Levites did as Moses commanded, and about 3,000 men fell dead that day among the people. Afterward Moses said, “Today you have been dedicated to the LORD, since each man went against his son and his brother. Therefore you have brought a blessing on yourselves today.” The following day Moses said to the people, “You have committed a grave sin. Now I will go up to the LORD; perhaps I will be able to atone for your sin.” So Moses returned to the LORD and said, “Oh, these people have committed a grave sin; they have made a god of gold for themselves. Now if You would only forgive their sin. But if not, please erase me from the book You have written.”
