Verse 1 The day of Pentecost; the fiftieth day; that is, the day after the expiration of seven weeks from the Passover. It was celebrated by the Jews as the anniversary of the giving of the law on Mount Sinai. It would seem (comp. Acts 1:3) that there was an interval of eight or ten days between the ascension of Christ and this occasion, as he continued to appear to his disciples for forty days, and the day of Pentecost was the fiftieth.
