Hebrews 7:5
And verily they that are of the sons of Levi, who receive the office of the priesthood, have a commandment to take tithes of the people according to the law, that is, of their brethren, though they come out of the loins of Abraham:
Hebrews 7:9
And as I may so say, Levi also, who receiveth tithes, payed tithes in Abraham.
