Adam Clarke on Acts 24:20

Any evil doing in me while I stood before the council - The Jews of Asia, the most competent witnesses, though my declared enemies, and they who stirred up the persecution against me, should have been here: why are they kept back? Because they could prove nothing against me. Let these, therefore, who are here, depose, if they have found any evil in me, or proved against me, by my most virulent adversaries, when examined before them in their council at Jerusalem.
