Hebrews 7:8

“And here men that die receive tithes, etc.,] The priests and Levites were not only men, and mortal men, subject to death, but they did die, and so did not continue, by reason of death, (<580724>Hebrews 7:24) but there he receiveth them, of whom it is witnessed that he liveth; which is to be understood of Melchizedek; who is not opposed to men, as if he was not a man, nor to mortal men, but to men that die; nor is he said to be immortal, but to live: and this may respect the silence of the Scripture concerning him, which gives no account of his death; and may be interpreted of the perpetuity of his priesthood, and of his living in his antitype Christ; and the testimony concerning him is in…”

“Second point of superiority: Melchisedec's is an enduring, the Levitical a transitory, priesthood. As the law was a parenthesis between Abraham's dispensation of promise of grace, and its enduring fulfilment at Christ's coming (Rom 5:20, Greek, "The law entered as something adscititious and by the way"): so the Levitical priesthood was parenthetical and temporary, between Melchisedec's typically enduring priesthood, and its antitypical realization in our ever continuing High Priest, Christ. here--in the Levitical priesthood. there--in the priesthood after the order of Melchisedec.

They had no exemption from sickness, affliction, or bereavement, and death came to them with just as much certainty as he approached other men. The meaning of this is, that they are mortal like their brethren, and the design is to show the inferiority of their office by this fact. Its obvious and natural signification, in the apprehension of the…”

“And here - In the Levitical priesthood. But there - In the case of Melchisedec. He of whom it is testified that he liveth - Who is not spoken of as one that died for another to succeed him; but is represented only as living, no mention being made either of his birth or death. Hebrews 7:9”

“7:8 Melchizedek’s “immortality” (7:3) is one aspect of his superiority to the Levites: The Levites are men who die, but Melchizedek lives on.”

“men: Heb 7:23, Heb 9:27 he liveth: Heb 3:16, Heb 5:6, Heb 6:20, Heb 9:24, Heb 9:25; Joh 11:25, Joh 11:26, Joh 14:6, Joh 14:19; Rev 1:18 Hebrews 7:9”
