John Gill Commentary Hebrews 5:10

"named of God a high priest after the order of Melchizedek." — Hebrews 5:10 (ASV)

Called of God an high priest, after the order of
Melchisedec .
] (ytrbd le) , according to what is said of him, (Psalms 110:4) there is a resemblance between Melchizedek and Christ; many things that are said of the one, agree with the other: there is a likeness in Melchizedek to Christ; in his person, and what is said of him, that he was without father and mother; and in his office as a priest, and in the manner of his instalment into it; and in the antiquity, dignity, and perpetuity of it: and this is repeated for the further confirmation of Christ's priesthood, and is a conclusion of the truth of it from sufficient evidence: this does not so much design the constitution of Christ as priest, nor the call of him to that office, as the denomination or surnaming of him a priest of Melchizedek's order, because of the agreement between them; and contains a reason of Christ's being the author of eternal salvation, because he is a priest for ever; and prevents any objections against Christ's priesthood, and opens a way to discourse more largely concerning it.
