15 "But the Levitical priests who descend from Zadok, who faithfully took care of my Sanctuary when everyone else went off and left me, are going to come into my presence and serve me. They are going to carry out the priestly work of offering the solemn sacrifices of worship. Decree of God, the Master. They're the only ones permitted to enter my Sanctuary. They're the only ones to approach my table and serve me, accompanying me in my work. 17 "When they enter the gate complex of the inside courtyard, they are to dress in linen. No woolens are to be worn while serving at the gate complex of the inside courtyard or inside the Temple itself. They're to wear linen turbans on their heads and linen underclothes - nothing that makes them sweat. When they go out into the outside courtyard where the people gather, they must first change out of the clothes they have been serving in, leaving them in the sacred rooms where they change to their everyday clothes, so that they don't trivialize their holy work by the way they dress. 20 "They are to neither shave their heads nor let their hair become unkempt, but must keep their hair trimmed and neat. 21 "No priest is to drink on the job - no wine while in the inside courtyard. 22 "Priests are not to marry widows or divorcees, but only Israelite virgins or widows of priests. 23 "Their job is to teach my people the difference between the holy and the common, to show them how to discern between unclean and clean. 24 "When there's a difference of opinion, the priests will arbitrate. They'll decide on the basis of my judgments, laws, and statutes. They are in charge of making sure the appointed feasts are honored and my Sabbaths kept holy in the ways I've commanded. 25 "A priest must not contaminate himself by going near a corpse. But when the dead person is his father or mother, son or daughter, brother or unmarried sister, he can approach the dead. But after he has been purified, he must wait another seven days. Then, when he returns to the inside courtyard of the Sanctuary to do his priestly work in the Sanctuary, he must first offer a sin offering for himself. Decree of God, the Master.
28 "As to priests owning land, I am their inheritance. Don't give any land in Israel to them. I am their 'land,' their inheritance. They'll take their meals from the grain offerings, the sin offerings, and the guilt offerings. Everything in Israel offered to God in worship is theirs. The best of everything grown, plus all special gifts, comes to the priests. All that is given in worship to God goes to them. Serve them first. Serve from your best and your home will be blessed. 31 "Priests are not to eat any meat from bird or animal unfit for ordinary human consumption, such as carcasses found dead on the road or in the field."
