Leviticus 10:1-7 - The Deaths Of Nadab And Abihu
1 And Nadab and Abihu, the sons of Aaron, took either of them his censor, and put fire therein, and put cense upon; and brought strange fire before the LORD: which he commanded them not. 2 And there went a fire out from the LORD, and consumed them, and they died before the LORD. 3 Then Moses said unto Aaron, "This is it that the LORD spake, saying, 'I will be sanctified in them that come nigh me, and before all the people I will be glorified.'" And Aaron held his peace.
4 And Moses called Mishael and Elzaphan the sons of Uzziel the uncle of Aaron, and said unto them, "Go to, and carry your brethren from the holy place out of the host." 5 And they went to them and carried them in their albs out of the host, as Moses bade.
6 And Moses said unto Aaron, and unto Eleazar and Ithamar his eldest sons, "Uncover not your head, neither rent your clothes; lest ye die and wrath come upon all the people. Let your brethren, the whole house of Israel, beweep the burning which the LORD hath burnt. 7 But go ye not out from the door of the tabernacle of witness, lest ye die: for the anointing oil of the LORD is upon you." And they did as Moses bade.
