Hebrews 7:2-6

2and to him Abraham apportioned a tenth of everything. First, by the translation of his name, he is “King of Righteousness”; and then also King of Salem, which is “King of Shalom.”

3Without father, without mother, without genealogy, having neither beginning of days nor end of life but made like Ben-Elohim, he remains a kohen for all time.

4Now see how great this man is! Even Abraham the patriarch gave him a tenth out of the plunder.

5Indeed, those sons of Levi who receive the priesthood have, according to Torah, a command to collect a tithe from the people—that is, from their kin, although they have come out of the loins of Abraham.

6But this one—who did not have their genealogy—has collected tithes from Abraham and has blessed him, the one holding the promises.
