Numbers 16:5; Numbers 16:40

5 and he spoke to Korah and all his company, saying, "Tomorrow morning the LORD will show who is His, and who is holy, and will bring him near to Himself; even the one whom He will choose, He will bring near to Himself.

40 as a reminder to the sons of Israel that no layman who is not of the descendants of Aaron should come near to burn incense before the LORD ; so that he will not become like Korah and his company -just as the LORD had spoken to him through Moses.
