Leviticus 10:1-7 - The Deaths Of Nadab And Abihu
1 Nadab and Abihu, the sons of Aaron, each took his censer, and put fire in it, and laid incense on it, and offered strange fire before Yahweh, which he had not commanded them. 2 And fire came forth from before Yahweh, and devoured them, and they died before Yahweh. 3 Then Moses said to Aaron, "This is what Yahweh spoke of, saying, 'I will show myself holy to those who come near me, and before all the people I will be glorified.'" Aaron held his peace.
4 Moses called Mishael and Elzaphan, the sons of Uzziel the uncle of Aaron, and said to them, "Draw near, carry your brothers from before the sanctuary out of the camp." 5 So they drew near, and carried them in their coats out of the camp, as Moses had said.
6 Moses said to Aaron, and to Eleazar and to Ithamar, his sons, "Don't let the hair of your heads go loose, neither tear your clothes; that you don't die, and that he not be angry with all the congregation: but let your brothers, the whole house of Israel, bewail the burning which Yahweh has kindled. 7 You shall not go out from the door of the Tent of Meeting, lest you die; for the anointing oil of Yahweh is on you." They did according to the word of Moses.
