Who (Τινες). Clearly interrogative, not indefinite (some).

Did provoke (παρεπικραναν). First aorist active indicative of παραπικρινω, apparently coined by the LXX like παραπικρασμος (verse Hebrews 3:15) to which it points, exasperating the anger of God.

Nay, did not all (αλλ' ου παντες). "A favourite device of the diatribe style" (Moffatt), answering one rhetorical question with another (Luke 17:8) as in verses Hebrews 3:17; Hebrews 3:18, There was a faithful minority mentioned by Paul (1. Corinthians 10:7).
