21 On the day of Pentecost all the believers were meeting together in one place. 2 Suddenly, there was a sound from heaven like the roaring of a mighty windstorm, and it filled the house where they were sitting. 3 Then, what looked like flames or tongues of fire appeared and settled on each of them. 4 And everyone present was filled with the Holy Spirit and began speaking in other languages, as the Holy Spirit gave them this ability.
5 At that time there were devout Jews from every nation living in Jerusalem. 6 When they heard the loud noise, everyone came running, and they were bewildered to hear their own languages being spoken by the believers. 7 They were completely amazed. "How can this be?" they exclaimed. "These people are all from Galilee, 8 and yet we hear them speaking in our own native languages! 9 Here we are-Parthians, Medes, Elamites, people from Mesopotamia, Judea, Cappadocia, Pontus, the province of Asia, 10 Phrygia, Pamphylia, Egypt, and the areas of Libya around Cyrene, visitors from Rome 11 (both Jews and converts to Judaism), Cretans, and Arabs. And we all hear these people speaking in our own languages about the wonderful things God has done!" 12 They stood there amazed and perplexed. "What can this mean?" they asked each other. 13 But others in the crowd ridiculed them, saying, "They're just drunk, that's all!"

Commentary on Acts 2:1-4
(Read Acts 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.

The difference in languages which arose at Babel, has much hindered the spread of knowledge and religion. The instruments whom the Lord first employed in spreading the Christian religion, could have made no progress without this gift, which proved that their authority was from God.
