As he saith also in another place, Thou art a priest for ever after the order of Melchisedec.
Ver. 6. Thou art a high priest, &c.] The former proof was not so evident; but this puts the matter out of all question. A minister should use sound speech that cannot be contradicted; that he that is of the contrary part may be ashamed, having nothing reasonably to oppose, Titus 2:8. The Jew would object that Christ was not of the tribe of Levi, therefore no priest. The apostle answers; Yes, a priest, but after another order, and proves it. This is συμβιβαζειν, collatis testimoniis demonstrare, as Paul did, Acts 9:22, to confirm and assert.
