Rabbi Tovia Singer asks a poignant question: "How can you start a book (any book) in a later chapter and have any idea what it's about? You'd be lost and in trouble."
The problem many Christians have with Chapter 53 of Isaiah is they really have no idea what has come before it in the previous 52 Chapters.
Jews also who have no knowledge of Isaiah and all it includes fall prey to Christian Missionaries use of Chapter 53 of the prophet's book leading them to believe that Jesus is the Suffering Servant spoken of in this Chapter. Nothing could be further from the truth.

He and Rabbi Singer are in complete agreement on the original Hebrew rendering of these verses.
