Hebrew name (ישעיהו) meaning - "God (Yahweh) is salvation".
Isaiah was a prophet in the 8th-century BC Kingdom of Judah.
Jews and Christians consider the Book of Isaiah a part of their Biblical canon; he is the first listed (although not the earliest) of the neviim akharonim, the later prophets. Christians believe that Isaiah prophesied the virgin birth of Jesus Christ
Gregory of Nyssa (c. 335-395), believes that the Prophet Esaias (Isaiah) meaning - "knew more perfectly than all others the mystery of the religion of the Gospel."Jerome (c. 342-420) also lauds the Prophet Esias, 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."
Islam usually regards Isaiah as a Prophet (although he is not mentioned by name in the Quran). Muslims believe that he was one of the many prophets to have prophesied to the Jews after the reign of king David. He is said to have prophesied about the coming of prophet Muhammad.
