In Hebrews 5:5, Christ is appointed high priest as Son; 5:10 specifies the Melchizedek order—both emphasize divine appointment.

In Hebrews 5:6, the quote 'priest forever after Melchizedek' is the source for the same designation in 5:10.

In Hebrews 6:20, Jesus is explicitly called high priest after Melchizedek, directly repeating the title from 5:10.

Hebrews 7:11 elaborates that perfection was not through the Levitical priesthood, explaining why another priest after Melchizedek is needed.

Hebrews 7:17 directly quotes Psalm 110:4 affirming Christ as a priest forever after Melchizedek's order.

Genesis 14:18 introduces Melchizedek as priest of God Most High — the very figure and order appointed for Christ in this verse.
