Leviticus 10:1-6

1Now Nadab and Abihu, the sons of Aaron, each took his censer and put fire in it and laid incense on it and offered unauthorized fire before the LORD, which he had not commanded them. 2And fire came out from before the LORD and consumed them, and they died before the LORD. 3Then Moses said to Aaron, “This is what the LORD has said: ‘Among those who are near me I will be sanctified, and before all the people I will be glorified.’” And Aaron held his peace. 4And Moses called Mishael and Elzaphan, the sons of Uzziel the uncle of Aaron, and said to them, “Come near; carry your brothers away from the front of the sanctuary and out of the camp.” 5So they came near and carried them in their coats out of the camp, as Moses had said. 6And Moses said to Aaron and to Eleazar and Ithamar his sons, “Do not let the hair of your heads hang loose, and do not tear your clothes, lest you die, and wrath come upon all the congregation; but let your brothers, the whole house of Israel, bewail the burning that the LORD has kindled.
