I gave my voice against them.— St. Paul had no vote in the sanhedrim, nor do we certainly know that he was personally concerned in the death of any except Stephen, in whose condemnation there was no voting at all. But the meaning plainly is, that he instigated the people against them as much as he could in that instance, and any other that might occur, whether at Jerusalem or elsewhere; which, as we hinted on ch. Acts 22:4 might perhaps be more than are recorded. Accordingly the Syriac renders it, I joined with those who condemned them.
