Acts 4:4

The number of the men was about five thousand.— Dr. Benson concludes, that five thousand men were converted on this occasion, besides the three thousand mentioned before, chap. Acts 2:41. If it had been said, as there, that so many were added to the church, it would have determined the sense as he and others understand it; but the use of the word εγενηθη here, became, favours the interpretation,thatthewholenumber,includingthosewhohadbeenconverted before, became about five thousand. See ch. Acts 1:15 in the Greek. It is hardly to be thought, unless it were expressly asserted, that another day should be so much more remarkable for its number of converts, than that on which the Spirit descended. However, supposing only two thousand were now converted, it is a glorious proof of the truth of Christianity; and no example can be given of the philosophers, or any other teachers, succeeding so gloriously in making converts to such holy and self-denying doctrines.
