Exodus 32:23-28

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.’ 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!” Moses saw that Aaron had let the people get completely out of control, much to the amusement of their enemies. 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. 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.” The Levites obeyed Moses’ command, and about 3,000 people died that day.
