Numbers 16:16-18

16Moses said to Korah, ‘Tomorrow, you and your men must come to the Tent of Meeting. You must come to stand in front of the Lord. Aaron will be there too.

17Each of you must take a pot and you must put incense in it. You must put the pots on the altar in front of the Lord. That will be 250 pots. You yourself must do the same thing, as well as Aaron.’

18So each man took a pot. He put incense in it, and fire to burn it. They stood with Moses and Aaron at the door of the Tent of Meeting.
