(15) If ye will hear.--Rather, as before (Hebrews 3:7), if ye shall hear. The true connection of this verse is not easily decided. By many it is held that the words should be joined with what follows, and commence a new paragraph; but this does not seem probable. Either Hebrews 3:14 is parenthetical, so that this verse emphasises the reference to "today" in Hebrews 3:13; or the thought of the writer is that we must "hold fast the beginning of our confidence" in the presence of this divine warning--whilst day by day these words are addressed to us anew.

Verse 15. - While it is said, Today, etc. Commentators have found unnecessary difficulty in determining the connection of ἐν τῷ λέγεσθαι. Many, taking the words as the beginning of a new sentence, have been at pains to discover the apodosis to them. Cbrysostom, Grotius, Rosenmuller, and others find it in φοβηθῶμεν οϋν, Hebrews 4:1; notwithstanding the οϋν, which seems evidently to introduce a new sentence, and the long parenthesis which, on this supposition, intervenes. Others find it in μὴ σκληρύνητε ("harden not your hearts"), in the middle of the citation of ver. 16, as if the writer of the Epistle adopted these words as his own. Delitzsch finds it in ver. 16, taken as an interrogation (τίνες, not τινὲς: see below); thus: "When it is said, Today... harden not your hearts as in the provocation,... who did provoke? Nay, did not all?" The γὰρ after τίνες he accounts for by its idiomatic use found in such passages as Acts 8:31; Acts 19:35, conveying the sense of the English, "Why, who did provoke?" But this use of γὰρ, obvious in the texts adduced as parallel, would be forced here; the structure of the sentence does not easily lend itself to it. Still, this is the view taken by Tholuck, Bleek, De Wette, Lunemann, and others, as well as Delitzsch. But, notwithstanding such weighty support, difficulties are surely best avoided by taking ἐν τῷ λέγεσθαι, not as commencing a new sentence, but in connection with ver. 14 preceding, as it seems most natural to take it in the absence of any connecting particle to mark a new proposition. In this case the translation of the A.V. gives a fully satisfactory sense: "If we hold fast the beginning of our confidence firm unto the end, while it is still being said, To-day," etc.; i.e. (as in ver. 13) "so long as it is called Today." Ebrard, Alford, and others, taking the same view of the connection of the words, prefer the translation, "In that it is said." But the other seems more in accordance with the thought pervading the passage.

3:14-19 The saints' privilege is, they are made partakers of Christ, that is, of the Spirit, the nature, graces, righteousness, and life of Christ; they are interested in all Christ is, in all he has done, or will do. The same spirit with which Christians set out in the ways of God, they should maintain unto the end. Perseverance in faith is the best evidence of the sincerity of our faith. Hearing the word often is a means of salvation, yet, if not hearkened to, it will expose more to the Divine wrath. The happiness of being partakers of Christ and his complete salvation, and the fear of God's wrath and eternal misery, should stir us up to persevere in the life of obedient faith. Let us beware of trusting to outward privileges or professions, and pray to be numbered with the true believers who enter heaven, when all others fail because of unbelief. As our obedience follows according to the power of our faith, so our sins and want of care are according to the prevailing of unbelief in us.While it is said today,.... Exhort one another, and hold fast Christ and his Gospel, and faith and confidence therein; what follows is a repetition of the citation in Hebrews 3:7 in order to make a further improvement of it; which shows, that the words belong to the present times of the Gospel, and contain in them matter of moment, and great concern; and that Scripture instructions and exhortations are of perpetual use.
