20 where Jesus has gone as a forerunner on our behalf, having become a high priest for ever after the order of Melchizedek.
The Priestly Order of Melchizedek
7 For this Melchizedek, king of Salem, priest of the Most High God, met Abraham returning from the slaughter of the kings and blessed him, 2 and to him Abraham apportioned a tenth part of everything. He is first, by translation of his name, king of righteousness, and then he is also king of Salem, that is, king of peace.
