Exodus 32:26-28

New Revised Standard Version, Anglicised

²⁶ then Moses stood in the gate of the camp, and said, ‘Who is on the Lord’s side? Come to me!’ And all the sons of Levi gathered around him. ²⁷ He said to them, ‘Thus says the Lord, the God of Israel, “Put your sword on your side, each of you! Go back and forth from gate to gate throughout the camp, and each of you kill your brother, your friend, and your neighbour.”’ ²⁸ The sons of Levi did as Moses commanded, and about three thousand of the people fell on that day.
