Hebrews 7:16-20 Amplified Bible (AMP)

16. Who has been constituted a Priest, not on the basis of a bodily legal requirement [an externally imposed command concerning His physical ancestry], but on the basis of the power of an endless and indestructible Life.

17. For it is witnessed of Him, You are a Priest forever after the order (with the rank) of Melchizedek. [Ps. 110:4.]

18. So a previous physical regulation and command is cancelled because of its weakness and ineffectiveness and uselessness–

19. For the Law never made anything perfect–but instead a better hope is introduced through which we [now] come close to God.

20. And it was not without the taking of an oath [that Christ was made Priest],
