Ezekiel 40:46

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 the king put Benaiah the son of Jehoiada in his room over the host: and Zadok the priest did the king put in the room of Abiathar.

And thou shalt give to the priests the Levites that be of the seed of Zadok, which approach unto me, to minister unto me, saith the Lord God, a young bullock for a sin offering.

It shall be for the priests that are sanctified of the sons of Zadok; which have kept my charge, which went not astray when the children of Israel went astray, as the Levites went astray.

And he spake unto Korah and unto all his company, saying, Even to morrow the Lord will shew who are his, and who is holy; and will cause him to come near unto him: even him whom he hath chosen will he cause to come near unto him.

And ye shall keep the charge of the sanctuary, and the charge of the altar: that there be no wrath any more upon the children of Israel.

Then said he unto me, The north chambers and the south chambers, which are before the separate place, they be holy chambers, where the priests that approach unto the Lord shall eat the most holy things: there shall they lay the most holy things, and the meat offering, and the sin offering, and the trespass offering; for the place is holy.

The holy portion of the land shall be for the priests the ministers of the sanctuary, which shall come near to minister unto the Lord: and it shall be a place for their houses, and an holy place for the sanctuary.

Then Moses said unto Aaron, This is it that the Lord spake, saying, I will be sanctified in them that come nigh me, and before all the people I will be glorified. And Aaron held his peace.

And the fire upon the altar shall be burning in it; it shall not be put out: and the priest shall burn wood on it every morning, and lay the burnt offering in order upon it; and he shall burn thereon the fat of the peace offerings. The fire shall ever be burning upon the altar; it shall never go out.

To be a memorial unto the children of Israel, that no stranger, which is not of the seed of Aaron, come near to offer incense before the Lord; that he be not as Korah, and as his company: as the Lord said to him by the hand of Moses.

But now in Christ Jesus ye who sometimes were far off are made nigh by the blood of Christ.
