Numbers 16:5-7

Then he said to Korah and all his followers: “In the morning the LORD will show who belongs to him and who is holy, and he will have that person come near him. The man he chooses he will cause to come near him. You, Korah, and all your followers are to do this: Take censers and tomorrow put burning coals and incense in them before the LORD. The man the LORD chooses will be the one who is holy. You Levites have gone too far!”
