Numbers 16:36-50 ESV
Then the LORD spoke to Moses, saying, “Tell Eleazar the son of Aaron the priest to take up the censers out of the blaze. Then scatter the fire far and wide, for they have become holy. As for the censers of these men who have sinned at the cost of their lives, let them be made into hammered plates as a covering for the altar, for they offered them before the LORD, and they became holy. Thus they shall be a sign to the people of Israel.” So Eleazar the priest took the bronze censers, which those who were burned had offered, and they were hammered out as a covering for the altar, to be a reminder to the people of Israel, so that no outsider, who is not of the descendants of Aaron, should draw near to burn incense before the LORD, lest he become like Korah and his company—as the LORD said to him through Moses. But on the next day all the congregation of the people of Israel grumbled against Moses and against Aaron, saying, “You have killed the people of the LORD.” And when the congregation had assembled against Moses and against Aaron, they turned toward the tent of meeting. And behold, the cloud covered it, and the glory of the LORD appeared. And Moses and Aaron came to the front of the tent of meeting, and the LORD spoke to Moses, saying, “Get away from the midst of this congregation, that I may consume them in a moment.” And they fell on their faces. And Moses said to Aaron, “Take your censer, and put fire on it from off the altar and lay incense on it and carry it quickly to the congregation and make atonement for them, for wrath has gone out from the LORD; the plague has begun.” So Aaron took it as Moses said and ran into the midst of the assembly. And behold, the plague had already begun among the people. And he put on the incense and made atonement for the people. And he stood between the dead and the living, and the plague was stopped. Now those who died in the plague were 14,700, besides those who died in the affair of Korah. And Aaron returned to Moses at the entrance of the tent of meeting, when the plague was stopped.
