Numbers 16:11

7 and tomorrow you are to place fire and incense in them in the presence of the LORD. Then the man the LORD chooses will be the one who is holy. It is you sons of Levi who have taken too much upon yourselves!”

8 Moses also said to Korah, “Now listen, you sons of Levi!

9 Is it not enough for you that the God of Israel has separated you from the congregation of Israel and brought you near to Himself to perform the work at the LORD’s tabernacle, and to stand before the congregation to minister to them?

10 He has brought you near, you and all your fellow Levites, but you are seeking the priesthood as well.

11 Therefore, it is you and all your followers who have conspired against the LORD! As for Aaron, who is he that you should grumble against him?”

12 Then Moses summoned Dathan and Abiram, the sons of Eliab, but they said, “We will not come!

13 Is it not enough that you have brought us up out of a land flowing with milk and honey to kill us in the wilderness? Must you also appoint yourself as ruler over us?

14 Moreover, you have not brought us into a land flowing with milk and honey or given us an inheritance of fields and vineyards. Will you gouge out the eyes of these men? No, we will not come!”

15 Then Moses became very angry and said to the LORD, “Do not regard their offering. I have not taken one donkey from them or mistreated a single one of them.”
