Adam Clarke on Acts 10:30

Four days ago I was fasting until this hour - It was then about three o'clock in the afternoon; and it appears that Cornelius had continued his fasts from three o'clock the preceding day to three o'clock the day following; not that he had fasted four days together, as some supposes for even if he did fast four days consecutively, he ate one meal on each day. It is however necessary to remark that the word νηϚευων, fasting is wanting in ABC, one other; the Coptic, Ethiopic, Armenian, and Vulgate; but it has not been omitted in any edition of the Greek Testament.
