Acts 2:1-13 The Coming Of The Holy Spirit-Languages Understood.
It is possible for a group of people to gather together in one place, but it is not always possible for them to be of “one accord,” but such was this group of followers on the Day of Pentecost (v. 1). Also known as the feast of weeks or harvest, Pentecost occurred 50 days after the seventh Sabbath (Cf. Ex. 23:16; 34:22; Lev. 23:15-21; Nu. 28:26-31; Dt. 16:9-12). It was the second of the three feasts that all males in the covenant community had to attend (along with the feasts of unleavened bread and tabernacles-Ex. 23:14-19). It started with a day for the offering of one’s firstfruits of the harvest. It is fitting, therefore, that the Spirit would come on the day of the firstfruits of what would continue to be a great harvest of redemption.
Three things happened showing that the Spirit had come-they heard the sound “as of a rushing mighty wind” (v. 2a), they saw “divided tongues, as of fire” (v. 2b), and “they were all filled with the Holy Spirit and began to speak with other tongues, as the Spirit gave them utterance” (vv. 3-4). The word for tongues is the word used for spoken languages. The people in Jerusalem, who had come from all over, each heard them speak in their own language-thus began the spread of the gospel seed, “the wonderful works of God” (vv. 5-11). Not all were convinced of course. All were “amazed and perplexed,” and some even mocked, but it could not be denied that people heard them speak in their own languages (vv. 12-13).
