Acts 2:1

When the day of pentecost was fully come Of this feast, which had its name from πεντηκοστη, pentecostee, (which signifies the fiftieth day,) because it was celebrated fifty days after the passover, see notes on Leviticus 23:15. As our Lord was crucified at one of the great Jewish feasts, it was fit that he should be glorified at another. And this of pentecost was chosen with peculiar propriety, as next succeeding that of the passover, at which he suffered; and also as it was celebrated in commemoration of the giving of the law from mount Sinai, and as the first- fruits were then offered and anointed, Exodus 19:1; Exodus 19:11; Leviticus 23:17. To these answered the fuller discovery of the gospel on this occasion, and the anointing of the first-fruits of the Christian Church by the effusion of the Spirit. At the pentecost of Sinai, in the Old Testament, and the pentecost of Jerusalem, in the New, were 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. And as the Jewish Church was constituted at the former of these periods, it was fit that the incorporation of the Christian Church should be dated from the latter. As further reasons why it was peculiarly proper that this time should be chosen for effecting this wonderful miracle, it may be observed, 1st, That as great multitudes of people were wont to assemble at Jerusalem at all the Jewish feasts, so it is probable that the peculiar solemnity of this feast, the general expectation of the Messiah that now prevailed among them, and the length of the days, as it was about the middle of summer, would bring greater numbers thither on this occasion than usually attended at the festivals. This would make the miracle the more public, and cause the fame of it to be spread the sooner and farther, which would contribute much to the propagation of the gospel among all nations, and make way for greater regard to the apostles, when they came to the countries where the people lived who had been spectators of this great event, and upon returning home, reported it to their friends and neighbours. 2d, As this feast of pentecost happened on the first day of the week, by the effusion of the Holy Spirit on this day, added to the resurrection of Christ taking place on it, still greater honour was put on the day, and it was more manifestly confirmed to be the Christian sabbath, the day which the Lord had appointed to be a standing memorial in his church of those two wonderful events. This not only justifies us in observing that day, under the title of the Lord's day, but directs us, in observing it, to give God praise, particularly for those two great blessings. They were all with one accord in one place In what place we are not told, whether in the temple, where they attended at public times, (Luke 24:53,) or whether in their own upper room, where they met at other times; but it was at Jerusalem, because it had been the place which God had chosen to put his name there, and the prophets had foretold that from thence the word of the Lord should go forth to all nations; (Isaiah 2:3; Micah 4:2;) and it was now the place of the general rendezvous of all devout people, where God had promised to meet and bless them; and here, therefore, he meets them with this blessing of blessings. It is probable that the ALL here mentioned, included the whole one hundred and twenty who were together when Matthias was chosen. The word ομοθυμαδον, rendered with one accord, implies that they were united in their views, intentions, and affections, and that there was no discord or strife among them, as there sometimes had been while their Master was with them. Doubtless, they were also united in their desire and expectation of the baptism of the Holy Ghost, the power from on high, which Christ had promised them; and in praying earnestly and importunately for it whenever they met together, which it appears they were in the habit of doing daily.
