“For hee testifieth; Thou art a Priest for euer, after the order of Melchisedec.”
1611 King James Version (KJV)
Heb 7:17 Thou art a priest for ever, etc. See Ps 110:4. This declares that the Christ shall be a priest, a priest forever, a priest not of the order of Aaron, but of Melchizedek; a priest-king whose office abideth continually (Heb 7:3).
