And when. To be fulfilled is taken in this place for to come. For Luke beareth record again of their perseverance, when he saith that they stood all in one place until the time which was set them. Hereunto serveth the adverb, with one accord Furthermore, we have before declared why the Lord did defer the sending of his Spirit a whole month and a half. But the question is, why he sent him upon that day chiefly. I will not refute that high and subtle interpretation of Augustine, that like as the law was given to the old people fifty days after Easter, being written in tables of stone by the hand of God, so the Spirit, whose office it is to write the same in our hearts, did fulfill that which was figured in the giving of the law as many days after the resurrection of Christ, who is the true Passover. Notwithstanding, whereas he urgeth this his subtle interpretation as necessary, in his book of Questions upon Exodus, and in his Second Epistle unto Januarius, I would wish him to be more sober and modest therein. Notwithstanding, let him keep his own interpretation to himself. In the mean season, I will embrace that which is more sound. Upon the feast day, wherein a great multitude was wont to resort to Jerusalem, was this miracle wrought, that it might be more famous. And truly by means hereof was it spread abroad, even unto the uttermost parts and borders of the earth. [1] For the same purpose did Christ oftentimes go up to Jerusalem upon the holy days, [2] (John 2, 5, 7,10, 12,) to the end those miracles which he wrought might be known to many, and that in the greater assembly of people there might be the greater fruit of his doctrine. For so will Luke afterward declare, that Paul made haste that he might come to Jerusalem before the day of Pentecost, not for any religion's sake, but because of the greater assembly, that he might profit the more, (Acts 20:16.) Therefore, in making choice of the day, the profit of the miracle was respected: First, that it might be the more extolled at Jerusalem, because the Jews were then more bent to consider the works of God; and, secondly, that it might be bruited abroad, even in far countries. They called it the fiftieth day, beginning to reckon at the first-fruits.

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 that it occurred 50 days after the first day of the Feast of the Passover. This feast was also called the Feast of Weeks, from the circumstance that it followed a succession of weeks, Exodus 34:22; Numbers 28:26; Deuteronomy 16:10. It was also a harvest festival, and was accordingly called the Feast of Harvest; and it was for this reason that two loaves made of new meal were offered on this occasion as first-fruits, Leviticus 23:17, Leviticus 23:20; Numbers 28:27-31.
Was fully come - When the day had arrived. The word used here means literally "to be completed," and as employed here refers, not to the day itself, but to the completion of the interval which was to pass before its arrival (Olshausen). See Luke 9:51. Compare Mark 1:15; Luke 1:57. This fact is mentioned, that the time of the Pentecost had come, or fully arrived, to account for what is related afterward, that there were so many strangers and foreigners present. The promised influences of the Spirit were withheld until the greatest possible number of Jews should be present at Jerusalem at the same time, and thus an opportunity be afforded of preaching the gospel to vast multitudes in the very place where the Lord Jesus was crucified, and also an opportunity be afforded of sending the gospel by them into distant parts of the earth.
They were all - Probably not only the apostles, but also the 120 people mentioned in Acts 1:15.
With one accord - See Acts 1:14. It is probable that they had continued together until this time, and given themselves entirely to the business of devotion.
In one place - Where this was cannot be known. Commentators have been much divided in their conjectures about it. Some have supposed that it was in the upper room mentioned in Acts 1:13; others that it was a room in the temple; others that it was in a synagogue; others that it was among the promiscuous multitude that assembled for devotion in the courts of the temple. See Acts 2:2. It has been supposed by many that this took place on the first day of the week; that is, on the Christian Sabbath. But there is a difficulty in establishing this. There was probably a difference among the Jews themselves as to the time of observing this festival: The Law said that they should reckon seven sabbaths; that is seven weeks, "from the morrow after the sabbath," Leviticus 23:15. By this Sabbath the Pharisees understood the second day of the Passover, on whatever day of the week it occurred, which was kept as a day of holy convocation, and which might be called a Sabbath. But the Karaite Jews, or those who insisted on a literal interpretation of the Scriptures, maintained that by the Sabbath here was meant the usual Sabbath, the seventh day of the week. Consequently, with them, the day of Pentecost always occurred on the first day of the week; and if the apostles fell in with their views, the day was fully come on what is now the Christian Sunday. But if the views of the Pharisees were followed, and the Lord Jesus had with them kept the Passover on Thursday, as many have supposed, then the day of Pentecost would have occurred on the Jewish Sabbath, that is, on Saturday (Kuinoel; Lightfoot). It is impossible to determine the truth on this subject. Nor is it of much importance. According to the later Jews, the day of Pentecost was kept also as a festival to commemorate the giving of the Law on Mount Sinai; but no trace of this custom is to be found in the Old Testament.

When the day of pentecost was fully come - The feast of pentecost was celebrated fifty days after the passover, and has its name πεντηκοστη from πεντηκοντα, fifty, which is compounded of πεντε, five, and ηκοντα, the decimal termination. It commenced on the fiftieth day reckoned from the first day of unleavened bread, i.e. on the morrow after the paschal lamb was offered. The law relative to this feast is found in Leviticus 23:15, Leviticus 23:16, in these words: And ye shall count unto you from the morrow after the Sabbath, from the day that ye brought the sheaf of the wave-offering; seven Sabbaths shall be complete: even unto the morrow after the seventh Sabbath shall ye number fifty days. This feast was instituted in commemoration of the giving the law on Mount Sinai; and is therefore sometimes called by the Jews, שמחת תורה shimchath torah, the joy of the law, and frequently the feast of weeks. There is a correspondence between the giving of the law, which is celebrated by this feast of pentecost, together with the crucifixion of our Lord, which took place at the passover, and this descent of the Holy Spirit, which happened at this pentecost.
1. At the passover, the Israelites were delivered from Egyptian bondage: this was a type of the thraldom in which the human race were to Satan and sin.
2. At the passover Jesus Christ, who was typified by the paschal lamb, was sacrificed for the sin of the world, and by this sacrifice redemption from sin and Satan is now procured and proclaimed.
3. On the pentecost, God gave his law on Mount Sinai, accompanied with thunderings and lightnings. On the pentecost, God sent down his Holy Spirit, like a rushing mighty wind; and tongues of fire sat upon each disciple, in order that, by his influence, that new law of light and life might be promulgated and established. Thus, the analogy between the Egyptian bondage and the thraldom occasioned by sin - the deliverance from Egypt, and the redemption from sin - the giving of the law, with all its emblematic accompaniments, and the sending down the Holy Spirit, with its symbols of light, life, and power, has been exactly preserved.
4. At the Jewish passover, Christ was degraded, humbled, and ignominiously put to death: at the following festival, the pentecost, he was highly glorified; and the all conquering and ever during might of his kingdom then commenced. The Holy Spirit seems to have designed all these analogies, to show that, through all preceding ages, God had the dispensation of the Gospel continually in view; and that the old law and its ordinances were only designed as preparatives for the new.
They were all with one accord in one place - It is probable that the All here mentioned means the one hundred and twenty spoken of Acts 1:15, who were all together at the election of Matthias. With one accord, ὁμοθυμαδον; this word is very expressive: it signifies that all their minds, affections, desires, and wishes, were concentred in one object, every man having the same end in view; and, having but one desire, they had but one prayer to God, and every heart uttered it. There was no person uninterested - none unconcerned - none lukewarm; all were in earnest; and the Spirit of God came down to meet their united faith and prayer. When any assembly of God's people meet in the same spirit they may expect every blessing they need.
In one place. - Where this place was we cannot tell: it was probably in the temple, as seems to be intimated in Acts 2:46, where it is said they were daily ὁμοθυμαδον εν τῳ ἱερῳ, with one accord in the temple; and as this was the third hour of the day, Acts 2:15, which was the Jewish hour of morning prayer, as the ninth hour was the hour of evening prayer, Acts 3:1, it is most probable that the temple was the place in which they were assembled.

And (1) when the day of Pentecost was (a) fully come, they were (b) all with one accord in one place.
(1) The Apostles being gathered together on a most solemn feast day in one place, that it might evidently appear to all the world that they all had one office, one Spirit, and one faith, are by a double sign from heaven authorised, and anointed with all the most excellent gifts of the Holy Spirit, and especially with an extraordinary and necessary gift of tongues.
(a) Literally, "was fulfilled": that is, was begun, as in (Luke 2:21). For the Hebrews say that a day or a year is fulfilled or ended when the former days or years are ended, and the other has begun; (Jeremiah 25:12): "And it will come to pass that when seventy years are fulfilled, I will visit, etc." For the Lord did not bring his people home after the seventieth year was ended, but in the seventieth year: Now the day of Pentecost was the fiftieth day after the feast of the Passover.
(b) The twelve apostles, who were to be the patriarchs as it were of the Church.

And when the day of Pentecost was fully come,.... 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 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 this feast by, is but one day (l); in the captivity they kept two days (m), as they did for the beginning of the year, because of the uncertainty of calculations; but the sense is, when the whole fifty days from the passover to this time were fully come, or fulfilled, when the fiftieth day from thence, which was properly the day of Pentecost, was come: on the second day of the passover, on the sixteenth of Nisan, the sheaf of the first fruits was offered up; after which, and not before, it was lawful to reap the corn, Leviticus 23:10 from this time the Jews reckoned their feast of weeks, or seven weeks, or fifty days; see Exodus 34:22 which measured out the time of their harvest. Now the last of these fifty days was the day of Pentecost, on which day was offered the two wave loaves, as a thanksgiving that their harvest was ended. Josephus calls (n) this feast by the same name that Luke here does; and says (o), the Jews so call it, from the number of the days, that is fifty; and so R. Song Jarchi (p) calls this day, , "the fiftieth day": on this day, the Jews say (q), the law was given; and observe (r), that "from the day that Israel went out of Egypt, unto the day that the law was given, were fifty days.
And on this day, and which was the first day of the week, the Spirit was poured forth upon the disciples; the Gospel began to be preached to all nations, and a harvest of souls was gathered in:
they were all with one accord in one place; in two ancient copies of Beza's, and in some others it is read, "all the apostles"; Matthias, and the eleven, with whom he was numbered, who are last spoken of, in Acts 1:26. Though this need not be restrained to the twelve apostles, but may be understood of the hundred and twenty, on whom, as well as on the apostles, the Holy Ghost might be poured forth, that so they might speak with tongues; since among these were many ministers of the Gospel, as the seventy disciples, and it may be more; and that his extraordinary gifts should be bestowed on others, is but what was afterwards done; see Acts 8:17 and though there were so many of them together, they were very unanimous and peaceable; there were no jars nor contentions among them; they were of the same mind and judgment in faith and practice, and of one heart and soul, and had a cordial affection for one another; and were all in one place, which seems to be the temple; see Acts 2:46. And indeed, no other place or house could hold so many as came to hear them, of which number three thousand were converted,

We cannot forget how often, while their Master was with them there were strifes among the disciples which should be the greatest; but now all these strifes were at an end. They had prayed more together of late. Would we have the Spirit poured out upon us from on high, let us be all of one accord. And notwithstanding differences of sentiments and interests, as there were among those disciples, let us agree to love one another; for where brethren dwell together in unity, there the Lord commands his blessing. A rushing mighty wind came with great force. This was to signify the powerful influences and working of the Spirit of God upon the minds of men, and thereby upon the world. Thus the convictions of the Spirit make way for his comforts; and the rough blasts of that blessed wind, prepare the soul for its soft and gentle gales. There was an appearance of something like flaming fire, lighting on every one of them, according to John Baptist's saying concerning Christ; He shall baptize you with the Holy Ghost, and with fire. The Spirit, like fire, melts the heart, burns up the dross, and kindles pious and devout affections in the soul; in which, as in the fire on the altar, the spiritual sacrifices are offered up. They were all filled with the Holy Ghost, more than before. They were filled with the graces of the Spirit, and more than ever under his sanctifying influences; more weaned from this world, and better acquainted with the other. They were more filled with the comforts of the Spirit, rejoiced more than ever in the love of Christ and the hope of heaven: in it all their griefs and fears were swallowed up. They were filled with the gifts of the Holy Ghost; they had miraculous powers for the furtherance of the gospel. They spake, not from previous though or meditation, but as the Spirit gave them utterance.

DESCENT OF THE SPIRIT--THE DISCIPLES SPEAK WITH TONGUES--AMAZEMENT OF THE MULTITUDE. (Acts 2:1-13)
when the day of Pentecost was fully come--The fiftieth from the morrow after the first Passover sabbath (Leviticus 23:15-16).
with one accord--the solemnity of the day, perhaps, unconsciously raising their expectations.

When the day of Pentecost was fully come. The entire period between it and the passover, the waiting period of the disciples, was filled full. Pentecost, one of the three great annual festivals of the Jews, lasted only one day, was on the fiftieth day from the morrow after the passover Sabbath (Leviticus 23:15-22). The Savior, crucified on Friday, was in the tomb on the passover Sabbath, and rose on Sunday, the day from whence the count began. The Sunday following would be the eighth day, and the fiftieth day would fall on Sunday, the first day of the eighth week. Hence, the ancient church observed Pentecost on the first day of the week. For fuller discussion, see Meyer, Howson and Milligan on this passage. All agree that Pentecost came on Sunday. Pentecost was the feast of the grain harvest (Exodus 23:16; Exodus 34:22-23), and was also held by the Jews to be the anniversary of the giving of the law.
They were all . . . in one place. Not only the apostles, but the hundred and twenty disciples. They probably had an intimation that the promised day had come.

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. They were all with one accord in one place - So here was a conjunction of company, minds, and place; the whole hundred and twenty being present.
