Thus says the Lord GOD: ...they shall hallow My Sabbaths.

Ezekiel 44:22-28

22 They shall not take as wife a widow or a divorced woman, but take virgins of the descendants of the house of Israel, or widows of priests.23 And they shall teach My people the difference between the holy and the unholy, and cause them to discern between the unclean and the clean.24 In controversy they shall stand as judges, and judge it according to My judgments. They shall keep My laws and My statutes in all My appointed meetings, and they shall hallow My Sabbaths.25 They shall not defile themselves by coming near a dead person. Only for father or mother, for son or daughter, for brother or unmarried sister may they defile themselves.26 After he is cleansed, they shall count seven days for him.27 And on the day that he goes to the sanctuary to minister in the sanctuary, he must offer his sin offering in the inner court," says the Lord God.28 "It shall be, in regard to their inheritance, that I am their inheritance. You shall give them no possession in Israel, for I am their possession.

31 The priests shall not eat anything, bird or beast, that died naturally or was torn by wild beasts.
