Hebrews 7:16-24

16who has been constituted not according to law of fleshly commandment, but according to power of indissoluble life.

17For it is borne witness, Thou art a priest for ever according to the order of Melchisedec.

18For there is a setting aside of the commandment going before for its weakness and unprofitableness,

19(for the law perfected nothing,) and the introduction of a better hope by which we draw nigh to 1God.

20And by how much [it was] not without the swearing of an oath;

21(for they are become priests without the swearing of an oath, but he with the swearing of an oath, by him who said, as to him, The Lord has sworn, and will not repent [of it], Thou [art] priest for ever [according to the order of Melchisedec];)

22by so much Jesus became surety of a better covenant.

23And they have been many priests, on account of being hindered from continuing by death;

24but he, because of his continuing for ever, has the priesthood unchangeable.
