Exodus 32:27-29

KJ2000(i) 27 And he said unto them, Thus says the LORD God of Israel, Put every man his sword by his side, and go in and out 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 children of Levi did according to the word of Moses: and there fell of the people that day about three thousand men. 29 For Moses had said, Consecrate yourselves today to the LORD, even every man upon the cost of his son, and his brother; that he may bestow upon you a blessing this day.
