As symbols preceded, tokens followed. The essential fact of Pentecost is neither the sound and fire, nor the speaking with other tongues, but the communication of the Holy Spirit. The sign and result of that was the gift of utterance in various languages, not their own, nor learned by ordinary ways. No twisting of the narrative can weaken the plain meaning of it, that these unlearned Galileans spake in tongues which their users recognised to be their own. The significance of the fact will appear presently, but first note the attestation of it by the multitude.
Of course, the foreign-born Jews, who, from motives of piety, however mistaken, had come to dwell in Jerusalem, are said to have been 'from every nation under heaven,' by an obvious and ordinary license. It is enough that, as the subsequent catalogue shows, they came from all corners of the then known world, though the extremes of territory mentioned cover but a small space on a terrestrial globe.
The 'sound' of the rushing wind had been heard hurtling through the city in the early morning hours, and had served as guide to the spot. A curious crowd came hurrying to ascertain what this noise of tempest in a calm meant, and they were met by something more extraordinary still. Try to imagine the spectacle. As would appear from verse 33, the tongues of fire remained lambently glowing on each head ('which ye see'), and the whole hundred and twenty, thus strangely crowned, were pouring out rapturous praises, each in some strange tongue. When the astonished ears had become accustomed to the apparent tumult, every man in the crowd heard some one or more speaking in his own tongue, language, or dialect, and all were declaring the mighty works of God; that is, probably, the story of the crucified, ascended Jesus.
We need not dwell on subordinate questions, as to the number of languages represented there, or as to the catalogue in verses 9 and 10. But we would emphasise two thoughts. First, the natural result of being filled with God's Spirit is utterance of the great truths of Christ's Gospel. As surely as light radiates, as surely as any deep emotion demands expression, so certainly will a soul filled with the Spirit be forced to break into speech. If professing Christians have never known the impulse to tell of the Christ whom they have found, their religion must be very shallow and imperfect. If their spirits are full, they will overflow in speech.
Second, Pentecost is a prophecy of the universal proclamation of the Gospel, and of the universal praise which shall one day rise to Him that was slain. 'This company of brethren praising God in the tongues of the whole world represented the whole world which shall one day praise God in its various tongues' (Bengel). Pentecost reversed Babel, not by bringing about a featureless monopoly, but by consecrating diversity, and showing that each language could be hallowed, and that each lent some new strain of music to the chorus.
It prophesied of the time when 'men of every tribe, and tongue, and people, and nation' should lift up their voices to Him who has purchased them unto God with His blood. It began a communication of the Spirit to all believers which is never to cease while the world stands. The mighty rushing sound has died into silence, the fiery tongues rest on no heads now, the miraculous results of the gifts of the Spirit have passed away also, but the gift remains, and the Spirit of God abides for ever with the Church of Christ.
