Numbers 16:35-40

35Fire came from the Lord and consumed the 250 men who were offering incense.

36Then the Lord said to Moses,

37“Tell Eleazar, son of the priest Aaron, to take the incense burners out of the fire and scatter the coals and incense somewhere else, because the incense burners have become holy.

38The 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.”

39So 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,

40following 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.
