a Bible passage
15 It is even more obvious when another priest arises, resembling Melchizedek,
15. Another proof that the law, or economy, is changed, namely, forasmuch as Christ is appointed Priest, "not according to the law of a carnal (that is, a mere outward) commandment," but "according to the power of an indissoluble (so the Greek) life." The hundred tenth Psalm appoints Him "for ever" (Heb 7:17). The Levitical law required a definite carnal descent. In contrast stands "the power"; Christ's spiritual, inward, living power of overcoming death. Not agreeably to a statute is Christ appointed, but according to an inward living power.
far more—Greek, "more abundantly."
for that—"seeing that," literally, "if"; so Ro 5:10.
after the similitude of Melchisedec—answering to "after the order of Melchisedec" (Heb 5:10). The "order" cannot mean a series of priests, for Melchisedec neither received his priesthood from, nor transmitted it to, any other mere man; it must mean "answering to the office of Melchisedec." Christ's priesthood is similar to Melchisedec's in that it is "for ever" (Heb 7:16, 17).
another—rather as Greek, "a different."
