Leviticus 10:1-7 - The Deaths Of Nadab And Abihu
1 Then Aaron's sons, Nadab and Abihu, each took his fire pan and put fire in it, set incense on it, and presented strange fire before the Lord, which he had not commanded them to do. 2 So fire went out from the presence of the Lord and consumed them so that they died before the Lord. 3 Moses then said to Aaron, "This is what the Lord spoke: 'Among the ones close to me I will show myself holy, and in the presence of all the people I will be honored.'" So Aaron kept silent.
4 Moses then called to Mishael and Elzaphan, the sons of Uzziel, Aaron's uncle, and said to them, "Come near, carry your brothers away from the front of the sanctuary to a place outside the camp." 5 So they came near and carried them away in their tunics to a place outside the camp just as Moses had spoken.
6 Then Moses said to Aaron and to Eleazar and Ithamar his other two sons, "Do not dishevel the hair of your heads and do not tear your garments, so that you do not die and so that wrath does not come on the whole congregation. Your brothers, all the house of Israel, are to mourn the burning which the Lord has caused, 7 but you must not go out from the entrance of the Meeting Tent lest you die, for the Lord's anointing oil is on you." So they acted according to the word of Moses.
