Jesus like Melchizedek

¹¹ If perfection could have been attained through the Levitical priesthood – and indeed the law given to the people established that priesthood – why was there still need for another priest to come, one in the order of Melchizedek, not in the order of Aaron? ¹² For when the priesthood is changed, the law must be changed also. ¹³ He of whom these things are said belonged to a different tribe, and no one from that tribe has ever served at the altar. ¹⁴ For it is clear that our Lord descended from Judah, and in regard to that tribe Moses said nothing about priests. ¹⁵ And what we have said is even more clear if another priest like Melchizedek appears, ¹⁶ one who has become a priest not on the basis of a regulation as to his ancestry but on the basis of the power of an indestructible life. ¹⁷ For it is declared:

‘You are a priest for ever,
    in the order of Melchizedek.’

¹⁸ The former regulation is set aside because it was weak and useless ¹⁹ (for the law made nothing perfect), and a better hope is introduced, by which we draw near to God.

²⁰ And it was not without an oath! Others became priests without any oath, ²¹ but he became a priest with an oath when God said to him:

‘The Lord has sworn
    and will not change his mind:
    “You are a priest for ever.”’

²² Because of this oath, Jesus has become the guarantor of a better covenant.
