Hebrews 7:3-5

Young's Literal Translation

³ without father, without mother, without genealogy, having neither beginning of days nor end of life, and being made like to the Son of God, doth remain a priest continually.

⁴ And see how great this one [is], to whom also a tenth Abraham the patriarch did give out of the best of the spoils,

⁵ and those, indeed, out of the sons of Levi receiving the priesthood, a command have to take tithes from the people according to the law, that is, their brethren, even though they came forth out of the loins of Abraham;
