Hebrews 8:7

Εἰ γὰρ … ἄμεμπτος. Whereas it was as he has said ἀσθενής and ἀνωφελής and σαρκίνη (Hebrews 7:16; Hebrews 7:18). The difference between the writer’s treatment of the relation between Christianity and Judaism and St Paul’s mode of dealing with the same subject consists in this:—to St Paul the contrast between the Law and the Gospel was that between the Letter and the Spirit, between bondage and freedom, between Works and Faith, between Command and Promise, between threatening and mercy. All these polemical elements disappear almost entirely from the Epistle to the Hebrews, which regards the two dispensations as furnishing a contrast between Type and Reality. This was the more possible to Apollos, or one of similar training to his, because he regards Judaism not so much in the light of a Law as in the light of a Priesthood and a system of worship. Like those who had been initiated into the ancient mysteries the Christian convert from Judaism could say ἔφυγον κακόν, εὗρον ἄμεινον—“I fled the bad, I found the better”; not that Judaism was in any sense intrinsically and inherently “bad” (Romans 7:12), but that it became so when it was preferred to something so much more Divine.

οὐκ ἂν ἐζητεῖτο. There would not have been—as we know there was—any demand for a second.
