Hebrews 7:3-5

21st Century King James Version

³ Without father, without mother and without descent, having neither beginning of days nor end of life, but made like unto the Son of God, he abideth a priest continually.

⁴ Now consider how great this man was, unto whom even the patriarch Abraham gave a tenth of the spoils.

⁵ And verily, those who are of the sons of Levi, who receive the office of the priesthood, have a commandment to take tithes from the people according to the law — that is, from their brethren — though they come out of the loins of Abraham.
