What does Numbers 16:10 mean?

God picked you out from everyone else in Israel, brought you close to Himself, and let you serve in His tent. He even let all your relatives, the Levites, come near too. But now you want even more—you want to be priests as well. Numbers 16:10 - Modern Text Bible

(Moses is calling out Korah and his followers for not being satisfied with their special role as Levites. They’re pushing for more power, wanting the priesthood itself.)
