Ezequiel 44:24

24 "'In any dispute, the priests are to serve as judges and decide it according to my ordinances. They are to keep my laws and my decrees for all my appointed festivals, and they are to keep my Sabbaths holy.

24 And in a controversy they shall stand to judge; according to mine ordinances shall they judge it: and they shall keep my laws and my statutes in all my appointed feasts; and they shall hallow my sabbaths.
