Matthew Poole and continuators on Acts 24:6

6 Who also hath gone about to profane the temple: whom we took, and would have judged according to our law.

By bringing into the Temple (as they falsly suggested) uncircumcised persons: But Tertullus does not mention this, or shew in what Paul had prophaned the Temple; for Felix himself being uncircumcised, it would have reflected upon him too much, to be accounted, by the Iews, amongst such prophane ones, as were enough to defile their Temple and Worship.

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 Chap. 21.28. And this was their aim all along, viz. to take away his Life.
