2:28, 29 Moses had earlier prayed that Israel as a whole would be a nation of prophets (Num. 11:29), and Joel also predicted this as part of Israel’s glorious future. Peter proclaimed that the vision began to find fulfillment at Pentecost with the coming of the Holy Spirit (Acts 2:16–21), who empowers believers to bear witness to Jesus Christ (Acts 1:8). By introducing this prophecy with “the last days” (Acts 2:17), Peter links it with other prophecies regarding Israel’s messianic future and so teaches that Pentecost inaugurates the promised new age (cf. 1 Pet. 1:10–12).
