Homilies on the Epistle to the Hebrews

^4. “Now consider” (says he) “how great this man is to whom even the Patriarch Abraham gave the tenth of the spoils.” Up to this point he has been applying the type: henceforward he boldly shows him [Melchisedec] to be more glorious than the Jewish realities. But if he who bears a type of Christ is so much better not merely than the priests, but even than the forefather himself of the priests, what should one say of the reality? You see how super-abundantly he shows the superiority.

“Now consider” (he says) “how great this man is to whom even the Patriarch Abraham gave a tenth out of the choice portions.” Spoils taken in battle are called “choice portions.” And it cannot be said that he gave them to him as having a part in the war, because (he said) he met him “returning from the slaughter of the kings,” for he had staid at home (he means), yet [Abraham] gave him the first-fruits of his labors.
