Exodus 32:27-29

New American Standard Bible

²⁷ And he said to them, “This is what the Lord, the God of Israel says: ‘Every man of you put his sword on his thigh, and go back and forth from gate to gate in the camp, and kill every man his brother, and every man his friend, and every man his ^[a]neighbor.’” ²⁸ So ^(A)the sons of Levi did ^[b]as Moses instructed, and about three thousand men of the people fell that day. ²⁹ Then Moses said, “^[c]Dedicate yourselves today to the Lord—for every man has been against his son and against his brother—in order that He may bestow a blessing upon you today.”
