¹¹So if the priesthood of Levi, on which the law was based, could have achieved the perfection God intended, why did God need to establish a different priesthood, with a priest in the order of Melchizedek instead of the order of Levi and Aaron?#7:11 Greek the order of Aaron? ¹²And if the priesthood is changed, the law must also be changed to permit it. ¹³For the priest we are talking about belongs to a different tribe, whose members have never served at the altar as priests. ¹⁴What I mean is, our Lord came from the tribe of Judah, and Moses never mentioned priests coming from that tribe. ¹⁵This change has been made very clear since a different priest, who is like Melchizedek, has appeared. ¹⁶Jesus became a priest, not by meeting the physical requirement of belonging to the tribe of Levi, but by the power of a life that cannot be destroyed. ¹⁷And the psalmist pointed this out when he prophesied,“You are a priest forever in the order of Melchizedek.”#7:17 Ps 110:4.
