HEB 7:11

11 [God] gave his laws to his people at the same time he gave regulations about the priests. So, if what the priests who were descended from Levi did could have provided a way for God to completely [forgive] people [for disobeying those laws], certainly no other priest like Melchizedek would have been necessary. [RHQ] Instead, priests who were descended from Aaron, [Levi’s descendant, would have been adequate].
