2:4 And they were all filled with the Holy Ghost, and began to speak with {c} other tongues, as the {d} Spirit gave them utterance.
(c) He calls them other tongues which were not the same as the apostles commonly used, and Mark calls them new tongues.
(d) By this we understand that the apostles were not speaking one language and then another by chance at random, or as eccentric men used to do, but that they kept in mind the languages of their hearers: and to be short, that they only spoke as the Holy Spirit directed them to speak.
2:4 They were all filled with the Holy Spirit. All the disciples present. To be filled implies that the human spirit within was overwhelmed by, or immersed in, the Holy Spirit. The baptism of the Spirit was not a sprinkling, but an outpouring that overwhelmed the human spirit.
Began to speak. This was the Beginning. See Lu 24:47 Ac 11:15.
With other tongues. In other languages (Revised Version). In the languages of all the different countries from which Jews had come up to Pentecost. Many would be unable to understand the Hebrew dialect of Judea in that period, and hence, they must be preached to in the tongue of their own country if they understood. That the gospel on this, the first day the Great Commission was ever preached, was preached in all tongues, symbolized the fact that it is for all nations.
As the Spirit gave them utterance. They were not allowed to preach the Great Commission until now, in order that every word uttered on this day might be the word of the Spirit, not of man. The words were to be spoken to an audience, not of those in Jerusalem only, but to our whole race in all time, in order to show how sinners are to be saved under the gospel.
2:4 And they began to speak with other tongues - The miracle was not in the ears of the hearers, (as some have unaccountably supposed,) but in the mouth of the speakers. And this family praising God together, with the tongues of all the world, was an earnest that the whole world should in due time praise God in their various tongues. As the Spirit gave them utterance - Moses, the type of the law, was of a slow tongue; but the Gospel speaks with a fiery and flaming one.
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.
