Concerning the greatness of Melchisedec, after whose order Christ is a high priest, Heb 7:1-4. The Levites had authority to take tithes of the people; yet Abraham, their representative, paid tithes to Melchisedec, Heb 7:5-10. Perfection cannot come by the Mosaic law, else there could be no need for another priest after the order of Melchisedec, according to the prediction of David in Psa 110:1-7, which priest is sprung from a tribe to which the priesthood, according to the law, did not appertain; but Christ is a priest for ever, not according to the law, but after the order of an endless life, Heb 7:11-17. The law, therefore, is disannulled, because of its unprofitableness and imperfection; and Christ has an unchangeable priesthood, Heb 7:18-24. He is therefore able always to save them that come unto him, being in every respect a suitable Savior; and he has offered up himself for the sins of the people, Heb 7:25-27. The law makes those priests who have infirmity; but he who is consecrated by the oath is perfect, and endures for ever, Heb 7:28.
