Exodus 32
Moses sends kill the idolaters
25 And when Moses saw that the people were naked, because Aaron had stripped to shame among their enemies,
26 He put his feet Moses in the camp of the door, and said, Who is the Lord, come to me. So they gathered unto him all the sons of Levi.
27 And he said unto them, Thus saith the Lord, the God of Israel, Put every man his sword upon his thigh: and pass over and become the gate of the camp in the door, 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 And Moses said, Consecrate today your hands to the Lord; because every man against his son, and against his brother, and this for him you today to give the blessing.
