Ezekiel 44:15-16

“ ‘But the priests who are Levites and descendants of Zadok took care of my Holy Place when Israel left me, so they may come near to serve me. They may stand in my presence to offer me the fat and blood of the animals they sacrifice, says the Lord GOD. They are the only ones who may enter my Holy Place. Only they may come near my table to serve me and take care of the things I gave them to do.
