Acts 26:10

I also did. It seems strange to think that Paul, the great hero of the early church, Apostle to the Gentiles and author of nearly a third of the NT, was at one time a bright star in the firmament of Judaism, well esteemed among the Jews (see chs. 7:58; 8:1; 9:1, 2; 22:4, 5). He had once been promoted to high honor (cf. AA 102) and entrusted with important responsibilities (Acts 9:1, 2) by the very men who now so vehemently accuse him, or by their immediate successors. His work as persecutor had not resulted from a burst of anger, but was the planned campaign of a devout man, ambitious to serve his nation and church and utterly ruthless in attaining his ends. Furthermore, these activities had centered in Jerusalem, where his enemies, the more bitter because they had once been friends, were now scheming to put him to death (Acts 25:1-3).

Put to death. Only the death of Stephen is mentioned specifically by Luke. Evidently there were others for whose death Paul had been responsible.

Gave my voice. That is, cast my vote.
