Heb Hebrews, chapter Epistle to the Hebrews, chapter 7
And for as much as it is not without an othe (for these are made Priestes without an othe: But this is made with an othe by him that said vnto him, The Lord hath sworne, and will not repent, Thou art a Priest for euer, after the order of Melchi-sedec) Psa 110:4
