Abraham paid tithes

1. Heb. 7: 5-6, 9
     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:
     6 But he whose descent is not counted from them received tithes of Abraham, and blessed him that had the promises.

     9 And as I may so say, Levi also, who receiveth tithes, payed tithes in Abraham.
2. Alma 13: 15
     15 And it was this same Melchizedek to whom Abraham paid tithes; yea, even our father Abraham paid tithes of one-tenth part of all he possessed.
