Hebrews chapter 7

For this Melchisedec, king of Salem, priest of the most high God, who met Abraham returning from the slaughter of the kings, and blessed him;

Without father, without mother, without descent, having neither beginning of days, nor end of life; but made like unto the Son of God; abideth a priest continually.

And verily they that are of the sons of Levi, who receive the office of the priesthood, have a commandment to take tithes of the people according to the law, that is, of their brethren, though they come out of the loins of Abraham:

And without all contradiction the less is blessed of the better.

And as I may so say, Levi also, who receiveth tithes, payed tithes in Abraham.

If therefore perfection were by the Levitical priesthood, (for under it the people received the law,) what further need was there that another priest should rise after the order of Melchisedec, and not be called after the order of Aaron?

For he of whom these things are spoken pertaineth to another tribe, of which no man gave attendance at the altar.

And it is yet far more evident: for that after the similitude of Melchisedec there ariseth another priest,

For he testifieth, Thou art a priest for ever after the order of Melchisedec.

For the law made nothing perfect, but the bringing in of a better hope did; by the which we draw nigh unto God.

For those priests were made without an oath; but this with an oath by him that said unto him, The Lord sware and will not repent, Thou art a priest for ever after the order of Melchisedec:)

And they truly were many priests, because they were not suffered to continue by reason of death:

Wherefore he is able also to save them to the uttermost that come unto God by him, seeing he ever liveth to make intercession for them.

Who needeth not daily, as those high priests, to offer up sacrifice, first for his own sins, and then for the people's: for this he did once, when he offered up himself.
