8:1-8 The prophet is to write on a large roll, or on a metal tablet, words which meant, Make speed to spoil, hasten to the prey: pointing out that the Assyrian army should come with speed, and make great spoil. Very soon the riches of Damascus and of Samaria, cities then secure and formidable, shall be taken away by the king of Assyria. The prophet pleads with the promised Messiah, who should appear in that land in the fulness of time, and, therefore, as God, would preserve it in the mean time. As a gentle brook is an apt emblem of a mild government, so an overflowing torrent represents a conqueror and tyrant. The invader's success was also described by a bird of prey, stretching its wings over the whole land. Those who reject Christ, will find that what they call liberty is the basest slavery. But no enemy shall pluck the believer out of Emmanuel's hand, or deprive him of his heavenly inheritance.

thy land, O Immanuel—Though temporarily applied to Isaiah's son, in the full sense this is applicable only to Messiah, that Judea is His, was, and still is, a pledge that, however sorely overwhelmed, it shall be saved at last; the "head" is safe even now, waiting for the times of restoration (Ac 1:6); at the same time these words imply that, notwithstanding the temporary deliverance from Syria and Israel, implied in "Immanuel," the greatest calamities are to follow to Judah.
