And suddenly - It burst upon them at once. Though they were waiting for the descent of the Spirit, yet it is not probable that they expected it in this manner. As this was an important event, and one on which the welfare of the church depended, it was proper that the gift of the Holy Spirit should take place in some striking and sensible manner, so as to convince their own minds that the promise was fulfilled, and so as deeply to impress others with the greatness and importance of the event.

There came a sound - ἦχος ēchos. This word is applied to any noise or report. Hebrews 12:19, "the sound of a trumpet"; Luke 4:37, "The fame of him," etc. Compare Mark 1:28.

From heaven - Appearing to rush down from the sky. It was suited, therefore, to attract their attention no less from the direction from which it came, than on account of its suddenness and violence. Tempests blow commonly horizontally. This appeared to come from above; and this is all that is meant by the expression. "from heaven."

As of a rushing mighty wind - Literally, "as of a violent blast borne along" - φερομένης pheromenēs - rushing along like a tempest. Such a wind sometimes borne along so violently, and with such a noise, as to make it difficult even to hear the thunder in the gale. Such appears to have been the sound of this remarkable phenomenon. It does not appear that there was any wind, but the sudden sound was like such a sweeping tempest. It may be remarked, however, that the wind in the sacred Scriptures is often put as an emblem of a divine influence. See John 3:8. It is invisible, yet mighty, and thus represents the agency of the Holy Spirit. The same word in Hebrew רוּח ruwach and in Greek πνεῦμα pneuma is used to denote both. The mighty power of God may be denoted also by the violence of a tempest, 1 Kings 19:11; Psalm 29:1-11; Psalm 104:3; Psalm 18:10. In this place the sound as of a gale was emblematic of the mighty power of the Spirit, and of the effects which his coming would accomplish among people.

And it filled - Not the wind filled, But the sound. This is evident:

(1) Because there is no affirmation that there was any wind.

(2) the grammatical structure of the sentence will admit no other construction. The word "filled" has no nominative case but the word "sound": "and suddenly there was a sound as of a wind, and (the sound) filled the house." In the Greek, the word "wind" is in the genitive or possessive case. It may be remarked here that this miracle was really far more striking than the common supposition makes it to have been. A tempest would have been terrific. A mighty wind might have alarmed them. But there would have been nothing unusual or remarkable in this. Such things often happened; and the thoughts would have been directed of course to the storm as an ordinary, though perhaps alarming occurrence. But when all was still; when there was no storm, no wind, no rain, no thunder, such a rushing sound must have arrested their attention, and directed all minds to a phenomenon so unusual and unaccountable.

All the house - Some have supposed that this was a room in or near the temple. But as the temple is not expressly mentioned, this is improbable. It was probably the private dwelling mentioned in Acts 1:13. If it be said that such a dwelling could not contain so large a multitude as soon assembled, it may be replied that their houses had large central courts (See the notes on Matthew 9:2), and that it is not affirmed that the transactions recorded in this chapter occurred in the room which they occupied. It is probable that it took place in the court and around the house.

A sound from heaven - Probably thunder is meant, which is the harbinger of the Divine presence.

Rushing mighty wind - The passage of a large portion of electrical fluid over that place would not only occasion the sound, or thunder, but also the rushing mighty wind; as the air would rush suddenly and strongly into the vacuum occasioned by the rarefaction of the atmosphere in that place, through the sudden passage of the electrical fluid; and the wind would follow the direction of the fire. There is a good deal of similarity between this account and that of the appearance of God to Elijah, 1 Kings 19:11, 1 Kings 19:12, where the strong wind, the earthquake, and the fire, were harbingers of the Almighty's presence, and prepared the heart of Elijah to hear the small still voice; so, this sound, and the mighty rushing wind, prepared the apostles to receive the influences and gifts of the Holy Spirit. In both cases, the sound, strong wind, and fire, although natural agents, were supernaturally employed. See the note on Acts 9:7.

And suddenly there came a sound from heaven,.... Which is expressive of the original of the gifts and graces of the Spirit of God, which come from above, from heaven, from the Father of lights; and of the freeness of them, being unmerited; and so come suddenly, at an unawares, being unthought of, undesired, and unexpected, and so certainly undeserved; and may be a symbol of the sound of the Gospel, which from hence was to go forth into all the earth; and may likewise express the rise of that, and the freeness of the grace of God in it, and its sudden spread throughout the world:

as of a rushing mighty wind; it was not a wind, but like one; and the noise it made, was like the rushing noise of a strong and boisterous wind, that carries all before it: the Spirit of God is sometimes compared to the wind, because of the freeness of his operations; as that blows where it listeth, so he works when and where, and on whom he pleases; and also because of the power and efficacy of his grace, which is mighty and irresistible, and works with great energy upon the minds of men; and as the wind is secret and invisible, so the operations of the Spirit are in a manner secret and imperceptible unto men: this may likewise be applied to the Gospel, when it comes with the Holy Ghost, and with power; it makes its way into the heart, and throws down the strong holds of sin and Satan; there it works effectually, though secretly, and is the power of God to salvation:

and it filled all the house where they were sitting; which was the temple, or the upper room or chamber in it, where they were assembled; so in the Ethiopic confession of faith (s) it is said,

"the Holy Ghost descended upon the apostles, in the upper room of Zion;

this may be a symbol of the Gospel filling the whole world,

(s) Vid. Ludolph. not. in Claud. reg. Ethiop. Confess. p. 13.

A sound (ἦχος)

See on Luke 4:37.

Of a rushing mighty wind (φερομένης πνοῆς βιαίας)

Lit., of a mighty wind borne along. Πνοή is a blowing, a blast. Only here and Acts 17:25. Rev., as of the rushing of a mighty wind.

The house

Not merely the room. Compare Acts 1:13.

Were sitting

Awaiting the hour of prayer. See Acts 2:15.

And suddenly there came a sound from heaven as of a rushing mighty wind, and it filled all the house where they were sitting.

2:2 There came a sound. As this day, the day of the founding of the church, was to be a day of signs and wonders, the shedding forth of the Spirit was made perceptible to all. The sound was heard, the tongues of fire were seen, the word was spoken in many languages.

It filled all the house. The mighty sound. At the same time the disciples were filled with the Holy Spirit, their spirits baptized in the Spirit.

2:2 And suddenly there came a sound from heaven - So will the Son of man come to judgment. And it filled all the house - That is, all that part of the temple where they were sitting.

2. And suddenly there came a sound from heaven, as of a rushing mighty wind, &c.-"The whole description is so picturesque and striking that it could only come from an eye-witness" [Olshausen]. The suddenness, strength, and diffusiveness of the sound strike with deepest awe the whole company, and thus complete their preparation for the heavenly gift. Wind was a familiar emblem of the Spirit (Eze 37:9; Joh 3:8; 20:22). But this was not a rush of actual wind. It was only a sound "as of" it.

2:1-4 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.
