Hebrews 7:11-12
Jesus and the Priesthood of Melchizedek
7:11 So if perfection had in fact been possible through the Levitical priesthood – for on that basis the people received the law – what further need would there have been for another priest to arise, said to be in the order of Melchizedek and not in Aaron’s order?
7:12 For when the priesthood changes, a change in the law must come as well.
Hebrews 7:18-19
7:18 On the one hand a former command is set aside
because it is weak and useless,
7:19 for the law made nothing perfect. On the other hand a better hope is introduced, through which we draw near to God.
