Hebrews 7:3
3 He is without father or mother tor genealogy, having neither beginning of days nor end of life, but resembling the Son of God he continues a priest forever.
Hebrews 7:15–17
15 This becomes even more evident when another priest arises in the likeness of Melchizedek, 16 who has become a priest, not on the basis of a legal requirement concerning bodily descent, but by the power of an indestructible life. 17 For it is witnessed of him,
c“You are a priest forever,
after the order of Melchizedek.”
