Numbers 16:3-5

3And they gathered themselves together against Moses and against Aaron, and said to them, Ye take too much upon you, seeing all the congregation are holy, every one of them, and the LORD is among them: why then do ye raise yourselves above the congregation of the LORD?1

4And when Moses heard it, he fell upon his face:

5And he spoke to Korah and to all his company, saying, Even to morrow the LORD will show who are his, and who is holy; and will cause him to come near to him: even him whom he hath chosen will he cause to come near to him.
