Acts 2:1

“And when the day of Pentecost was fully come, etc.] Or “was come”, was begun and entered upon; for it was not over, or ended, it being but the third hour of the day, or nine of the clock in the morning, when Peter began his sermon; (see <440215>Acts 2:15). The Vulgate Latin and Syriac versions read, “when the days of Pentecost were fulfilled”; not that there were more days than one, kept at this festival; for though the feasts of passover and tabernacles were observed each of them seven days, according to the law, and eight days according to the Scribes, yet the feast of Pentecost was kept but one day; and hence it is often said by the Jews, that Atzereth, which is one of the names they call…”

“DESCENT OF THE SPIRIT--THE DISCIPLES SPEAK WITH TONGUES--AMAZEMENT OF THE MULTITUDE.

“And when the day of Pentecost - The word “Pentecost” is a Greek word signifying the 50th part of a thing, or the 50th in order. Among the Jews it was a applied to one of their three great feasts which began on the 50th day after the Passover. This feast was reckoned from the 16th day of the month Abib, or April, or the second day of the Passover. The paschal lamb was slain on the 14th of the month at evening, Leviticus 23:5; on the 15th day of the month was a holy convocation - the proper beginning of the feast; on the 16th day was the offering of the firstfruits of harvest, and from that day they were to reckon seven weeks, that is, 49 days, to the feast called the Feast of Pentecost, so…”

“At the pentecost of Sinai, in the Old Testament, and the pentecost of Jerusalem, in the New, where the two grand manifestations of God, the legal and the evangelical; the one from the mountain, and the other from heaven; the terrible, and the merciful one.

“2:1-4 Jews observed three great annual pilgrimage festivals, when many would go to the Temple in Jerusalem—Unleavened Bread (which includes Passover), Pentecost (Harvest), and Shelters (see Lev 23:1-44). On Pentecost, when the Jewish people were gathered in Jerusalem to celebrate the harvest of God’s blessings, and when the disciples were united and expectant as they gathered for prayer, the Holy Spirit came and filled the gathered believers.”
