Hebrews 7:3-5

Revised Geneva Translation

⁴ Now consider how great this man was to whom even the patriarch Abraham gave a tithe of the spoils.

⁵ For indeed those who are the children 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 brothers), though they came out of the loins of Abraham.
