Hebrews 7:10

8Here people who die receive tithes, but there one receives tithes of whom it is testified that he lives.

9We can say that through Abraham even Levi, who receives tithes, has paid tithes,

10for he was yet in the body of his father when Melchizedek met him.

11Now if perfection was through the Levitical priesthood (for under it the people have received the law), what further need was there for another priest to arise after the order of Melchizedek, and not be called after the order of Aaron?

12For the priesthood being changed, there is of necessity a change made also in the law.
