Come to me.” And all the sons of Levi gathered around him. 27And he said to them, “Thus says the Lord God of Israel, ‘Put your sword on your side each of you, and go to and fro from gate to gate throughout the camp, and each of you akill his brother and his companion and his neighbor.’” 28And the sons of Levi did according to the word of Moses. And that day about three thousand men of the people fell. 29And Moses said, “Today you have been bordained for the service of the Lord, each one at the cost of his son and of his brother, so that he might bestow a blessing upon you this day.”

Dead Sea Scroll, Septuagint; Masoretic Text lacks  Give to Levi
eyour Thummim,
and your Urim to your godly one,
fwhom you tested at Massah,
with whom you quarreled at the waters of Meribah;
9who said of his father and mother,
‘I regard them not’;
ghe disowned his brothers
and ignored his children.
For hthey observed your word
and kept your covenant.
10 iThey shall teach Jacob your rules
and Israel your law;
jthey shall put incense before you
and kwhole burnt offerings on your altar.
11Bless, O Lord, his substance,
and laccept the work of his hands;
crush the loins of his adversaries,
of those who hate him, that they rise not again.”
