“And it shall come to pass in the last days, saith God, I will pour out of my Spirit upon all flesh: and your sons and your daughters shall prophesy, and your young men shall see visions, and your old men shall dream dreams:”
King James Version (KJV)
2:17 The times of the Messiah are frequently called the last days, the Gospel being the last dispensation of Divine grace. I will pour out of my Spirit - Not on the day of pentecost only, upon all flesh - On persons of every age, sex, and rank. And your young men shall see visions - In young men the outward sense, are most vigorous, and the bodily strength is entire, whereby they are best qualified to sustain the shock which usually attends the visions of God. In old men the internal senses are most vigorous, suited to divine dreams. Not that the old are wholly excluded from the former, nor the young from the latter.
Ac 2:17 It shall come to pass in the last days. The phrase "Last days" was used by the Jews to denote the last dispensation, that of Christ. See Isa 2:2. I will pour out of my Spirit. A figurative expression to indicate abundant gifts of the Spirit. Upon all flesh. On all races, not on the Jews alone. Your sons and your daughters shall prophesy. "To prophesy" in the New Testament means to communicate religious truth by divine authority, as well as to foretell the future. The prophecy was fulfilled in the inspired speaking on Pentecost and afterwards, as well as by the daughters of Philip (21:9). It will be seen that both sexes are included. See visions . . . dream dreams. Such visions as that of Peter at Joppa (Ac 10:9-16). Such dreams as that of Paul at Troas, where he saw the Macedonian asking him to "Come and help us" (Ac 16:9).
