Numbers 16:3-5

3and they gathered themselves together against Moses and against Aaron, and said to them, It is enough; for all the assembly, all of them are holy, and Jehovah is among them; and why do ye lift up yourselves above the congregation of Jehovah?

4When Moses heard this, he fell on his face.

5And he spoke to Korah and to all his band, saying, Even to-morrow will Jehovah make known who is his, and who is holy; and he will cause him to come near to him; and him whom he has chosen, him will he cause to come near to him.
