Priest and king

Hebrews 5:6 As he saith also in another [place], Thou [art] a priest for ever after the order of Melchisedec.

Hebrews 7:1 For this Melchisedec, king of Salem, priest of the most high God, who met Abraham returning from the slaughter of the kings, and blessed him;... 17 For he testifieth, Thou [art] a priest for ever after the order of Melchisedec.... 21 (For those priests were made without an oath; but this with an oath by him that said unto him, The Lord sware and will not repent, Thou [art] a priest for ever after the order of Melchisedec:)

Psalms 110:4 The LORD hath sworn, and will not repent, Thou [art] a priest for ever after the order of Melchizedek.
