For what if? (ti gar ei?). But Westcott and Hort print it, Ti gar? ei. See Philippians 1:18 for this exclamatory use of ti gar (for how? How stands the case?). Some were without faith (hpisthsan). First aorist active indicative of apistew, old verb, to disbelieve. This is the common N.T. meaning ( Luke 24:11Luke 24:41 ; Acts 28:24 ; Romans 4:20 ). Some of them "disbelieved," these "depositaries and guardians of revelation" (Denney). But the word also means to be unfaithful to one's trust and Lightfoot argues for that idea here and in 2 Timothy 2:13 . The Revised Version renders it "faithless" there. Either makes sense here and both ideas are true of some of the Jews, especially concerning the Messianic promises and Jesus. The faithfulness of God (thn pistin tou qeou). Undoubtedly pisti has this sense here and not "faith." God has been faithful ( 2 Timothy 2:13 ) whether the Jews (some of them) were simply disbelievers or untrue to their trust. Paul can use the words in two senses in verse 2 Timothy 3 , but there is no real objection to taking hpisthsan, apistian, pistin, all to refer to faithfulness rather than just faith.
