The teaching of Melchizedek was full and replete, but the records of these days seemed impossible and fantastic to the later Hebrew priests, although many had some understanding of these transactions, at least up to the times of the en masse editing of the Old Testament records in Babylon.
Close in meaning, found by a language model. A match does not mean the teachings are the same.
For this Melchizedek, king of Salem, priest of God Most High, who met Abraham returning from the slaughter of the kings and blessed him, to whom also Abraham divided a tenth part of all (being first, by interpretation, “king of righteousness”, and then also “king of Salem”, which means “king of peace”, without father, without mother, without genealogy, having neither beginning of days nor end of life, but made like the Son of God), remains a priest continually.
Now if perfection was through the Levitical priesthood (for under it the people have received the law), what further need was there for another priest to arise after the order of Melchizedek, and not be called after the order of Aaron? For the priesthood being changed, there is of necessity a change made also in the law. For he of whom these things are said belongs to another tribe, from which no one has officiated at the altar. For it is evident that our Lord has sprung out of Judah, about which tribe Moses spoke nothing concerning priesthood. This is yet more abundantly evident, if after the likeness of Melchizedek there arises another priest, who has been made, not after the law of a fleshly commandment, but after the power of an endless life; for it is testified, “You are a priest forever, according to the order of Melchizedek.”
Now consider how great this man was, to whom even Abraham the patriarch gave a tenth out of the best plunder. They indeed of the sons of Levi who receive the priest’s office have a commandment to take tithes from the people according to the law, that is, of their brothers, though these have come out of the body of Abraham, but he whose genealogy is not counted from them has accepted tithes from Abraham, and has blessed him who has the promises. But without any dispute the lesser is blessed by the greater. Here people who die receive tithes, but there one receives tithes of whom it is testified that he lives. We can say that through Abraham even Levi, who receives tithes, has paid tithes, for he was yet in the body of his father when Melchizedek met him.
