Numbers 17:5

and in the morning you will see the glory of Yahweh, for He hears your grumblings against Yahweh; and what are we, that you grumble against us?”

Now the people became like those who complain of calamity in the ears of Yahweh. And Yahweh heard it and His anger was kindled, and the fire of Yahweh burned among them and consumed some of the outskirts of the camp.

and he spoke to Korah and all his congregation, saying, “Tomorrow morning Yahweh 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.

He sent Moses His servant, And Aaron, whom He had chosen.

Nor grumble, as some of them did, and were destroyed by the destroyer.
