And the LORD said unto me, Son of man, mark well, and behold with thine eyes, and hear with thine ears all that I say unto thee concerning all the ordinances of the house of the LORD, and all the laws thereof; and mark well the entering in of the house, with every going forth of the sanctuary.
in that ye have brought into my sanctuary strangers, uncircumcised in heart, and uncircumcised in flesh, to be in my sanctuary, to pollute it, even my house, when ye offer my bread, the fat and the blood, and they have broken my covenant because of all your abominations.
Yet they shall be ministers in my sanctuary, having charge at the gates of the house, and ministering to the house: they shall slay the burnt offering and the sacrifice for the people, and they shall stand before them to minister unto them.
Because they ministered unto them before their idols, and caused the house of Israel to fall into iniquity; therefore have I lifted up mine hand against them, saith the Lord GOD, and they shall bear their iniquity.
And they shall not come near unto me, to do the office of a priest unto me, nor to come near to any of my holy things, in the most holy place: but they shall bear their shame, and their abominations which they have committed.
¶ But the priests the Levites, the sons of Zadok, that kept the charge of my sanctuary when the children 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, saith the Lord GOD:
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.
And when they go forth into the outer court, even into the outer court to the people, they shall put off their garments wherein they ministered, and lay them in the holy chambers, Lev. 16.23 and they shall put on other garments; and they shall not sanctify the people with their garments.
And in controversy they shall stand in judgment; and they shall judge it according to my judgments: and they shall keep my laws and my statutes in all mine assemblies; and they shall hallow my sabbaths.
And they shall come at no dead person to defile themselves: Lev. 21.1-4 but for father, or for mother, or for son, or for daughter, for brother, or for sister that hath had no husband, they may defile themselves.
And the first of all the firstfruits of all things, and every oblation of all, of every sort of your oblations, shall be the priest's: ye shall also give unto the priest the first of your dough, that he may cause the blessing to rest in thine house. Num. 18.8-19
