15. The priests of the Levi tribe who are descendants of Zadok the priest were faithful to me, even when the rest of the Israelites turned away. And so, these priests will continue to serve as my priests and to offer the fat and the blood of sacrifices.
16. They will come into my temple, where they will offer sacrifices at my altar and lead others in worship.
17. When they come to the inner courtyard, they must wear their linen priestly clothes. My priests must never wear anything made of wool when they are on duty in this courtyard or in the temple.
18. Even their turbans and underwear must be made of linen to keep my priests from sweating when they work.
19. And before they leave to join the other people in the outer courtyard, they must take off their priestly clothes, then place them in the sacred rooms and put on their ordinary clothes. That way, no one will touch their sacred clothes and be harmed.
20. Priests must never shave their heads when they are mourning. But they must keep their hair properly trimmed and not let it grow too long.
21. They must not drink wine before going to the inner courtyard.
22. A priest must not marry a divorced woman; he can marry only a virgin from Israel or the widow of another priest.
23. Priests must teach my people the difference between what is sacred and what is ordinary, and between what is clean and what is unclean.
24. They will make decisions in difficult legal cases, according to my own laws. They must also observe the religious festivals my Law requires and must always respect the Sabbath.
25. Touching a dead body will make a person unclean. So a priest must not go near a dead body, unless it is one of his parents or children, or his brother or unmarried sister.
26. If a priest touches a dead body, he is unclean and must go through a ceremony to make himself clean. Then seven days later,
27. he must go to the inner courtyard of the temple and offer a sacrifice for sin. After that, he may once again serve as my priest. I, the Lord God, have spoken.
