Heb Hebrews, chapter Epistle to the Hebrews, chapter 7
Inasmuch as he was not made priest without the taking of an oath (for they indeed have been made priests without an oath), but he with an oath by him that says of him,
“The Lord swore and will not change his mind,
‘You are a priest forever,
according to the order of Melchizedek.’”7:21 Psalms 110:4Psa 110:4
