Then Isaiah the son of Amoz sent unto Hezekiah, saying: "Thus saith the LORD, the God of Israel: Whereas thou hast prayed to Me against Sennacherib king of Assyria,
this is the word which the LORD hath spoken concerning him: The virgin daughter of Zion hath despised thee and laughed thee to scorn; the daughter of Jerusalem hath shaken her head at thee.
Whom hast thou taunted and blasphemed? And against whom hast thou exalted thy voice? Yea, thou hast lifted up thine eyes on high, even against the Holy One of Israel!" (37:21–23)
The first verse of the Book of Isaiah states that Isaiah prophesied during the reigns of Uzziah (or Azariah), Jotham, Ahaz, and Hezekiah, the kings of Judah (Isaiah 1:1). Uzziah's reign was 52 years in the middle of the 8th century BCE, and Isaiah must have begun his ministry a few years before Uzziah's death, probably in the 740s BCE. Isaiah lived until the fourteenth year of Hezekiah's reign (who died 698 BCE). He may have been contemporary for some years with Manasseh. Thus Isaiah may have prophesied for as long as 64 years.
Gregory of Nyssa (c. 335–395), believed that the Prophet Isaiah "knew more perfectly than all others the mystery of the religion of the Gospel". Jerome (c. 342–420) also lauds the Prophet Isaiah, saying, "He was more of an Evangelist than a Prophet, because he described all of the Mysteries of the Church of Christ so vividly that you would assume he was not prophesying about the Future, but rather was composing a history of past events." Of specific note are the songs of the Suffering Servant, which Christians say are a direct prophetic revelation of the nature, purpose, and detail of the death of Jesus Christ.
The Book of Isaiah is quoted many times by New Testament Writers. Ten of those references are about the Suffering Servant, how he will suffer and die to save many from their sins, be buried in a rich man's tomb, and be a light to the Gentiles. The Gospel of John says that Isaiah "saw Jesus’ glory and spoke about him."
