(11) And God wrought special miracles by the hands of Paul.--The Greek phrase is negative: no common works of power--not such as one might meet with any day. (See Note on Acts 28:2, where the same phrase recurs.) The noun is that which was technically used by physicians for the healing "powers" or "virtues" of this or that remedy, and is so far, though used freely by other writers, characteristic of St. Luke.

19:8-12 When arguments and persuasions only harden men in unbelief and blasphemy, we must separate ourselves and others from such unholy company. God was pleased to confirm the teaching of these holy men of old, that if their hearers believed them not, they might believe the works.And God wrought special miracles by the hands of Paul. For the confirmation of the doctrine which he preached, and of his mission, as an apostle; and these were not any sort of miracles, common and vulgar ones, and much less things of chance, and what were merely accidental, as the word may signify; but they were rare and uncommon ones, and in which there was a visible display of the power of God; to whom as the efficient cause they are ascribed, the apostle being only an instrument God made use of.
