The prophecy; the prophetical writings, or word of prophecy, 2 Peter 1:19. Came not in old time by the will of man; the prophets spake not of themselves what and when they pleased. But holy men of God; prophets, called men of God, 1 Samuel 2:27, 1 Samuel 9:6 1 Kings 17:18, and elsewhere. They are here called holy, not only because of their lives, wherein they were examples to others, but because they were the special instruments of the Holy Ghost, who sanctified them to the work of preaching, and penning what he dictated to them. Spake as they were moved; or, carried out, or acted, i.e. elevated above their own natural abilities. This may imply the illumination of their minds with the knowledge of Divine mysteries, the gift of infallibility, that they might not err, of prophecy, to foretell things to come, and a peculiar instinct of the Holy Ghost, whereby they were moved to preach or write.
