Numbers 16:8-11

8Moses also said to Korah, “Listen, you Levites!

9Isn’t it enough for you that the God of Israel has separated you from the rest of the community of Israel? The Lord has brought you near himself to do the work for his tent and stand in front of the community to serve them.

10He has brought you and all the other Levites near himself, but now you demand to be priests.

11So you and all your followers have joined forces against the Lord! Who is Aaron that you should complain about him?”
