Numbers 16:5-7

5and he spoke to Korah and all his company, saying, “In the morning the Lord will show who belongs to Him, and who is holy, and will bring him near to Himself; the one whom He will choose He will bring near to Himself.

6Do this: Take censers for yourselves, Korah and all your company,

7then put fire in them and place incense on them in the presence of the Lord tomorrow; and the man whom the Lord chooses shall be the one who is holy. You have gone far enough, you sons of Levi.”
