actually you do not need to get a Hebrew scripture to read the book of Isaiah. In the old testament in the Bible that would be the 23rd book. The words spoken by the prophet have been kept accurately troughout the ages.

See Isaiah ch.3.
Immanuel or Emmanuel or Imanu'el (Hebrew עִמָּנוּאֵל "God [is] with us" consists of two Hebrew words: אֵל ('El, meaning 'God') and עִמָּנוּ (ʻImmānū, meaning 'with us'); Standard Hebrew ʻImmanuʼel, Tiberian Hebrew ʻImmānûʼēl). It is a theophoric name used in the Bible in Isaiah 7:14 and Isaiah 8:8. It appears once in the Christian New Testament: in Matthew's quotation of Isaiah 7:14.
Many Christians believe that the Book of Isaiah is important because Isaiah chapter 14 foretells the virgin birth of Jesus. They become incredulous when they learn that the author of Matthew actually relied on the Greek Septuagint (LXX), an early, flawed translation from the Hebrew texts. In the original text of Isaiah, there is no mention of a virgin, just of a young woman who would soon have a child and call him Immanuel. So, it is the Greek text that is best for the Christian faith, and this text departs from Isaiah's Hebrew in some important respects.For more information, please visit: http://christianity.answers.com/bible/the-book-of-isaiah-explained
