Hebrews 7:3-5

New Revised Standard Version, Anglicised

³ Without father, without mother, without genealogy, having neither beginning of days nor end of life, but resembling the Son of God, he remains a priest for ever.

⁴ See how great he is! Even^[a] Abraham the patriarch gave him a tenth of the spoils. ⁵ And those descendants of Levi who receive the priestly office have a commandment in the law to collect tithes^[b] from the people, that is, from their kindred,^[c] though these also are descended from Abraham.
