Introduction to Isaiah

Isaiah prophesied in the reigns of Uzziah, Jotham, Ahaz, and Hezekiah. He has been well called the evangelical prophet, on account of his numerous and full prophesies concerning the coming and character, the ministry and preaching, the sufferings and death of the Messiah, and the extent and continuance of his kingdom. Under the veil of the deliverance from Babylon, Isaiah points to a much greater deliverance, which was to be effected by the Messiah; and seldom does he mention the one, without alluding at the same time to the other; nay, he is often so much enraptured with the prospect of the more distant deliverance, as to lose sight of that which was nearer, and to dwell on the Messiah's person, office, character, and kingdom.
