Hebrews Chapter 7 Verse 4And 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 so, after he had patiently endured, he obtained the promise.

For men verily swear by the greater: and an oath for confirmation [is] to them an end of all strife.

Wherein God, willing more abundantly to shew unto the heirs of promise the immutability of his counsel, confirmed [it] by an oath:

That by two immutable things, in which [it was] impossible for God to lie, we might have a strong consolation, who have fled for refuge to lay hold upon the hope set before us:

Which [hope] we have as an anchor of the soul, both sure and stedfast, and which entereth into that within the veil;

Whither the forerunner is for us entered, [even] Jesus, made an high priest for ever after the order of Melchisedec.

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;

To whom also Abraham gave a tenth part of all; first being by interpretation King of righteousness, and after that also King of Salem, which is, King of peace;

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.

Now consider how great this man [was], unto whom even the patriarch Abraham gave the tenth of the spoils.

But he whose descent is not counted from them received tithes of Abraham, and blessed him that had the promises.

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

And here men that die receive tithes; but there he [receiveth them], of whom it is witnessed that he liveth.

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

For he was yet in the loins of his father, when Melchisedec met him.

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 the priesthood being changed, there is made of necessity a change also of the law.

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

For [it is] evident that our Lord sprang out of Juda; of which tribe Moses spake nothing concerning priesthood.

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