Exodus 32:27-29

Wycliffe Bible

²⁷ To which he said, The Lord God of Israel saith these things, A man put his sword upon his hip, go ye, and turn ye again from gate unto gate by the middle of the tents, and each man slay his brother, his friend, and [his] neighbour, which consented to this idolatry. (To whom he said, The Lord God of Israel saith these things, Each man put his sword on his hip, and then go ye through the midst of the camp, from one gate to the other, and back again, and each man kill his brother, his friend, and his neighbour, yea, all who consented to this idolatry.)

²⁸ And the sons of Levi did by the word of Moses, and as three thousand of men felled down in that day. (And the Levites obeyed Moses, and three thousand men fell down dead that day.)

²⁹ And Moses said, Ye have hallowed your hands today to the Lord, each man in his son, and [his] brother, that blessing be given to you. (And Moses said, Today ye have consecrated yourselves to the Lord, each man against his son, and against his brother, and so a blessing hath been given to you.)
