For anyone truly interested in understanding the truth about Isaiah 53, I suggest the following article which is cogently argued. Following are excerpts from the prelude and a link to the article. It should be read in its entirety. :
Isaiah 53 – A Jewish Perspective
Before engaging in an examination of Isaiah 53 itself, some preliminary issues must be considered. First is the issue of circular reasoning. Even if we interpret the chapter as the Christians do (forgetting for a minute the mistranslations and distortions of context which will be noted below), the most that could be said is this: Isaiah 53 is about someone who dies for the sins of others. People may have seen Jesus die, but did anyone see him die as an atonement for the sins of others? Of course not; this is simply the meaning which the New Testament gives to his death. Only if you already accept the New Testament teaching that his death had a non-visible, spiritual significance can you than go back to Isaiah and say, “see – the Prophet predicted what I already believe.”...
Second (and consistent with all Jewish teaching at the time), Jesus’ own disciples didn’t view Isaiah 53 as a messianic prophecy. For example, after Peter identifies Jesus as the Messiah (Matt. 16:16), he is informed that Jesus will be killed (Matt. 16:21). His response: “God forbid it, lord! This shall never happen to you” (Matt. 16:22)...Even Jesus didn’t see Isaiah 53 as crucial to his messianic claims – why else did he call the Jews children of the devil for not believing in him before the alleged resurrection (Jn. 8:39-47)? And why did he later request that God “remove this cup from me” (Mk. 14:36) – didn’t he know that a “removal of the cup” would violate the gentile understanding of Isaiah 53?
And third, even if we accept the gentile Christian interpretation of Isaiah 53, where is it indicated (either in Isaiah 53 or anywhere else in our Jewish Scriptures) that you must believe in this “Messiah” to get the benefits?
