Exodus 32:25-27

New Catholic Bible

²⁵ Moses saw that the people had lost control of themselves (for Aaron had let them run so wild that their enemies mocked them). ²⁶ So he stood at the gate to the camp and said, “Whoever is for the Lord, come to me!” All the sons of Levi gathered around him. ²⁷ He cried out to them, “Thus says the Lord, the God of Israel: Each man strap a sword to his side. Then pass back and forth in the camp from one gate to another and slay your brother, your companion, and your neighbor.”
