These are the names of the sons of Levi according to their generations: Gershon and Kohath and Merari; and the length of Levi’s life was one hundred and thirty-seven years.
So the Lord said to Aaron, “You and your sons and your father’s household with you shall bear the guilt in connection with the sanctuary, and you and your sons with you shall bear the guilt in connection with your priesthood.
