Exodus 32:26-28

Revised Standard Version Catholic Edition

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 themselves together to him. ²⁷ And he said to them, “Thus says the Lord God of Israel, ‘Put every man his sword on his side, and go to and fro from gate to gate throughout the camp, and slay every man his brother, and every man his companion, and every man his neighbor.’” ²⁸ And the sons of Levi did according to the word of Moses; and there fell of the people that day about three thousand men.
