Exodus 32:27-29

New Revised Standard Version, Anglicised

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. ²⁹ Moses said, ‘Today you have ordained yourselves^[a] for the service of the Lord, each one at the cost of a son or a brother, and so have brought a blessing on yourselves this day.’
