Isaiah had great religious and political influence during the reign of Hezekiah, king of Judah. Isaiah's ministry lasted about 40 years. It has been generally accepted that Isaiah began to prophesy about 740 B.C.
"Isaiah is the most quoted of all the prophets, being more frequently quoted by Jesus, Paul, Peter, and John (in his Revelation) than any other
Old TestamentT prophet. Likewise the Book of Mormon and the Doctrine and Covenants quote from Isaiah more than from any other prophet," states the dictionary in the LDS edition of the King James Bible. "The Lord told the Nephites that `great are the words of Isaiah,' and that all things Isaiah spoke of the house of Israel and of the gentiles would be fulfilled. (3 Ne. 23:1-3.)"The writings of Isaiah deal with events of his day as well as events beyond his time, some of which have already come to pass and others are yet to be. The bulk of Isaiah's prophecies deal with the coming of the Redeemer, both in His first appearance . . . and as the Great King at the last day, as the God of Israel.
"A major theme is that God requires righteousness of His people, and until they obey Him they will be smitten and scattered by their enemies. But in the end, Israel will be restored; the barren land will be made fruitful and able to support a large population; and the Lord, the Holy One of Israel, will dwell in the midst of His people, who will be called Zion."
