Hath gone about to profane the temple; by bringing into the temple (as they falsely suggested) uncircumcised persons: but Tertullus does not mention this, or show in what Paul had profaned the temple; for Felix himself being uncircumcised, it would have reflected upon him too much, to be accounted, by the Jews, amongst such profane ones, as were enough to defile their temple and worship. Would have judged according to our law; they had a law, it seems, whereby it was death to bring strangers into the temple; and some think, that by the Romans they had yet power allowed them to put it in execution: See Poole on "Acts 21:28". And this was their aim all along, viz. to take away his life.
