Hebrews 7:11 in the King James Version
If therefore perfection were by the Levitical priesthood, (for under it the people received the law,) what further need was there that another priest should rise after the order of Melchisedec, and not be called after the order of Aaron?
Context
10 for he was yet in the body of his father when Melchizedek met him.
11 Now 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?
12 For the priesthood being changed, there is of necessity a change made also in the law.
