Leviticus 10:1-7

NLT
New Living Translation

1Aaron’s sons Nadab and Abihu put coals of fire in their incense burners and sprinkled incense over them. In this way, they disobeyed the Lord by burning before him the wrong kind of fire, different than he had commanded. 2So fire blazed forth from the Lord’s presence and burned them up, and they died there before the Lord.
3Then Moses said to Aaron, “This is what the Lord meant when he said,
‘I will display my holiness
through those who come near me.
I will display my glory
before all the people.’”
And Aaron was silent.
4Then Moses called for Mishael and Elzaphan, Aaron’s cousins, the sons of Aaron’s uncle Uzziel. He said to them, “Come forward and carry away the bodies of your relatives from in front of the sanctuary to a place outside the camp.” 5So they came forward and picked them up by their garments and carried them out of the camp, just as Moses had commanded.
6Then Moses said to Aaron and his sons Eleazar and Ithamar, “Do not show grief by leaving your hair uncombed#10:6 Or by uncovering your heads. or by tearing your clothes. If you do, you will die, and the Lord’s anger will strike the whole community of Israel. However, the rest of the Israelites, your relatives, may mourn because of the Lord’s fiery destruction of Nadab and Abihu. 7But you must not leave the entrance of the Tabernacle#10:7 Hebrew Tent of Meeting; also in 10:9. or you will die, for you have been anointed with the Lord’s anointing oil.” So they did as Moses commanded.
