TSK · Numbers 17:3

Now these are the names of the sons of Levi, according to their records: Gershon, Kohath, and Merari.(The length of Levi’s life was 137 years.)

These are the names of the sons of Aaron: Nadab, the firstborn, and Abihu, Eleazar, and Ithamar.

But you and your sons with you are responsible for your priestly duties, for everything at the altar and within the curtain. And you must serve. I give you the priesthood as a gift for service, but the unauthorized person who approaches must be put to death.”

You are making a fatal mistake. For you sent me to the LORD your God and asked me,‘Pray to the LORD our God for us. Tell us what the LORD our God says and we will do it.’
