Ezekiel 44:15

And I will raise me up a faithful priest, that shall do according to that which is in mine heart and in my mind: and I will build him a sure house; and he shall walk before mine anointed for ever.

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 the chamber whose prospect is toward the north is for the priests, the keepers of the charge of the altar: these are the sons of Zadok among the sons of Levi, which come near to the LORD to minister unto him.

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.

Not given to wine, no striker, not greedy of filthy lucre; but patient, not a brawler, not covetous; One that ruleth well his own house, having his children in subjection with all gravity; (For if a man know not how to rule his own house, how shall he take care of the church of God?) Not a novice, lest being lifted up with pride he fall into the condemnation of the devil. Moreover he must have a good report of them which are without; lest he fall into reproach and the snare of the devil. Likewise must the deacons be grave, not doubletongued, not given to much wine, not greedy of filthy lucre; Holding the mystery of the faith in a pure conscience. And let these also first be proved; then let them use the office of a deacon, being found blameless.

And the things that thou hast heard of me among many witnesses, the same commit thou to faithful men, who shall be able to teach others also.
