Numbers 16:5-7

5Then he said to Korah and all his followers, “Tomorrow morning the LORD will reveal who belongs to Him1 and who is holy, and He will bring that person near to Himself. The one He chooses He will bring near to Himself. 6You, Korah, and all your followers are to do as follows: Take censers, 7and tomorrow you are to place fire and incense in them in the presence of the LORD. Then the man the LORD chooses will be the one who is holy. It is you sons of Levi who have taken too much upon yourselves!”
