15. But the priests the Levites, the sons of Zadok, that kept the charge of my sanctuary when the sons of Israel went astray from me, they shall come near to me to minister unto me, and they shall stand before me to offer unto me the fat and the blood, said the Lord GOD.
16. They shall enter into my sanctuary, and they shall come near to my table, to minister unto me, and they shall keep my charge.
17. And it shall come to pass, that when they enter in at the gates of the inner court, they shall be clothed with linen garments; and no wool shall come upon them, while they minister in the gates of the inner court and within.
18. They shall have linen bonnets upon their heads and shall have linen underwear upon their loins; they shall not gird themselves with any thing that causes sweat.
19. And when they go forth into the outer court, even into the outer court to the people, they shall put off their garments in which they ministered and lay them in the chambers of the sanctuary, and they shall put on other garments; and they shall not sanctify the people with their garments.
20. Neither shall they shave their heads, nor suffer their locks to grow long; they shall only cut their hair.
21. Neither shall any priest drink wine, when they enter into the inner court.
22. Neither shall they take for their wives a widow, nor her that is put away: but they shall take virgins of the seed of the house of Israel, or a widow that had a priest before.
23. And they shall teach my people the difference between the holy and profane and teach them to discern between the clean and the unclean.
