Leviticus 10:1-5

Aaron’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. So fire blazed forth from the LORD’s presence and burned them up, and they died there before the LORD. Then 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. Then 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.” So they came forward and picked them up by their garments and carried them out of the camp, just as Moses had commanded.
