Numbers 16:9-10

9The God of Israel has caused you Levites to be separate from all the other Israelites. He has brought you near to himself, to work in the Lord's Tent. He has chosen you to stand in front of all the people to serve them. But it seems that this is not enough for you.

10He has brought you, Korah, and all the other descendants of Levi near to himself. But it seems that you want to be priests as well.
