The Nations of Pentecost
In the first Christian century, Jewish communities were located primarily in the eastern Roman Empire, where Greek was the common language. There were Jewish communities as far west as Italy and as far east as Babylonia. In addition to people from the nations shown here, those present on the Day of Pentecost included visitors from Mesopotamia and even farther east, from Parthia, Media, and Elam (present-day Iran).
Pentecost was one of the three major Jewish festivals. From the Greek word for “fifty,” Pentecost was so named because it fell on the fiftieth day after the Sabbath of the Passover. Pentecost was also known as “the Feast of Weeks,” “the Firstfruits of the Wheat Harvest,” and “the Day of Firstfruits.” During this harvest celebration, the Jews brought to God the firstfruits of their harvest in thanksgiving, expecting that God would give the rest of the harvest as His blessing. This particular Day of Pentecost was the day of firstfruits of Christ’s church, the beginning of the great harvest of souls who would come to know Christ and be joined together through the work of the Holy Spirit. Note that the text does not say that the Spirit spoke through the apostles, but that the Spirit gave them the ability to speak in languages that they had not previously known. It appears that the “speaking in tongues” did not consist of proclaiming the gospel. Rather, the apostles were praising God’s mighty works.
Acts 2:1-4
2 When the Day of Pentecost had fully come, they were all with one accord in one place. 2 And suddenly there came a sound from heaven, as of a rushing mighty wind, and it filled the whole house where they were sitting. 3 Then there appeared to them divided tongues, as of fire, and one sat upon each of them. 4 And they were all filled with the Holy Spirit and began to speak with other tongues, as the Spirit gave them utterance.
