Hebrews 6:17

ἐν ᾧ περισσότερον.… “Wherefore God, being minded more abundantly to demonstrate to the heirs of the promise the immutability of His purpose, interposed with an oath.” ἐν ᾧ = διὸ (Theoph.), and see Winer, 484. It might be rendered “quae cum ita sint,” or “this being so”. The oath having among men this convincing power, God disregards the insult implied in any doubt of His word and condescending to human infirmity confirms His promise by an oath. περισσότερον neuter adjective for adverb (Hebrews 2:1) is to be construed with ἐπιδεῖξαι, the meaning of the comparative being “abundantius quam s ne juramento factum videretur” (Bengel). Carpzov renders by “ex abundanti,” and cites Philo, De Abrahamo c. 46 where the word of God is said to become an oath, ἕνεκα τοῦ τὴν διάνοιαν ἀκλινῶς καὶ παγίως ἔτι μᾶλλον ἢ πρότερον ἐρηρεῖσθαι. τοῖς κληρονόμοις, not exclusively the O.T. nor exclusively the N.T. heirs, neither Jews nor Gentiles, but all; see Hebrews 9:3, and Galatians 3:29. τὸ ἀμετάθετον τῆς βουλῆς αὐτοῦ, the unchangeable character of His purpose. [ἀμετάθ. 3Ma 5:1; 3Ma 5:12; Polybius with ἐπιβολή, ὁρμή, διάληψις. For use of adjective see Romans 2:4; Romans 8:3; 1 Corinthians 1:25, etc. Winer, p. 294.] ἐμεσίτευσεν ὅρκῳ, μεσιτεύω, belonging to later Greek, “to act as mediator,” but sometimes used transitively “to negotiate,” as in Polybius Hebrews 11:34; Hebrews 11:3. Other examples in Bleek. Here, however, it is used intransitively as in Josephus, Ant., vii. 8, 5. So the margin of A.V. “interposed himself by an oath,” improved in R.V. “interposed with an oath”. Cf. Josephus Ant., iv. 6, 7; ταῦτα δὲ ὀμνύοντες ἔλεγον καὶ θεὸν μεσίτην ὧν ὑπισχνοῦντο ποιούμενοι. “God descended, as it were, from His own absolute exaltation, in order, so to speak, to look up to Himself after the manner of men and take Himself to witness; and so by a gracious condescension confirm the promise for the sake of its inheritors” (Delitzsch). “He brought in Himself as surety, He mediated or came in between men and Himself, through the oath by Himself” (Davidson).
