Numbers 16:38-48

38 The incense burners of these men who sinned and lost their lives are holy, because they were offered to the LORD. Hammer them into thin metal sheets to cover the altar. This will be a sign to the Israelites."
39 So the priest Eleazar took the bronze incense burners which had been brought by those who had been burned to death. The incense burners were then hammered into thin metal sheets to cover the altar,
40 following the command that the LORD had given through Moses. The bronze-covered altar will remind Israel that no one but a descendant of Aaron can come near to burn incense to the LORD. Everyone else will die like Korah and his followers.
41 The next day the whole community of Israel complained to Moses and Aaron. They said, "You have killed the LORD's people."
42 The community came together to confront Moses and Aaron. When they turned toward the tent of meeting, they saw the smoke covering it, and the glory of the LORD appeared.
43 Then Moses and Aaron went to the front of the tent of meeting.
44 The LORD said to Moses,
45 "Get away from these people, and let me destroy them in an instant!" Immediately, they bowed with their faces touching the ground.
46 Moses said to Aaron, "Take your incense burner, put burning coals from the altar and incense in it, and go quickly into the community to make peace with the LORD for the people. The LORD is showing his anger; a plague has started."
47 Aaron took his incense burner, as Moses told him, and ran into the middle of the assembly, because the plague had already begun among the people. He put incense on the incense burner to make peace with the LORD for the people.
48 He stood between those who had died and those who were still alive, and the plague stopped.
