Hebrews 7:1-6
The Nature of Melchizedek’s Priesthood
7:1 Now this Melchizedek, king of Salem, priest of the most high God, met Abraham as he was returning from defeating the kings and blessed him.
7:2 To him also Abraham apportioned a tithe of everything. His name first means king of righteousness, then king of Salem, that is, king of peace.
7:3 Without father, without mother, without genealogy, he has neither beginning of days nor end of life but is like the son of God, and he remains a priest for all time.
7:4 But see how great he must be, if Abraham the patriarch gave him a tithe of his plunder.
7:5 And those of the sons of Levi who receive the priestly office have authorization according to the law to collect a tithe from the people, that is, from their fellow countrymen, although they too are descendants of Abraham.
7:6 But Melchizedek who does not share their ancestry collected a tithe from Abraham and blessed the one who possessed the promise.
