Exodus 32:19-30

19Then it happened, as soon as Moses came near the camp, he saw the calf and the dancing, and his anger burned hot. So he threw the tablets out of his hands, and smashed them at the foot of the mountain.

20Then he took the calf that they had made, burned it with fire, ground it to powder, scattered it on the surface of the water and made Bnei-Yisrael drink it.

21Then Moses said to Aaron, “What did this people do to you, to make you bring such a great sin upon them?”

22Aaron said, “Don’t be angry, my lord! You know these people yourself, and how they are set on evil.

23They said to me, ‘Make gods for us, to go before us! As for this Moses, the man that brought us up out of the land of Egypt, we don’t know what happened to him.’

24So I said to them, ‘Whoever has any gold, let them break it off.’ So they gave it to me and I threw it into the fire—and out came this calf!”

25When Moses saw that the people were unrestrained, because Aaron had let them run wild, to become a joke among their enemies,

26Moses stood at the gate of the camp and said, “Whoever is on Adonai’s side, let him come to me.” Then all the sons of Levi gathered themselves together to him.

27He said to them, “This is what Adonai, the God of Israel says, ‘Every man put on his sword, and go to and fro, from gate to gate throughout the camp, and slay his brother, his friend, and his neighbor.’”

28So the sons of Levi did as Moses said, and that day from among the people there fell about 3,000 men.

29Then Moses said, “Consecrate your hands today to Adonai so that He may give you a blessing today, for every man has been against his son and his brother.”

30So it happened the following day, Moses said to the people, “You have committed a horrendous sin. So now I will go up to Adonai—perhaps I can make atonement for your sin.”
