This thread summarizes primary Jewish objections to Jesus as the Servant in Isaiah 52:13-53:12 and rebuts them. I'm open to critiques.

To summarize the Jewish case: first, Isaiah, outside of the four Servant Songs, consistently calls collective Israel God's Servant ... ... e.g., Isa. 43:10. Second, Isa. 49:3, which is in the second Servant Songs, identifies the Servant as Israel. Third, the nations from Isa. 52:15 speak in Isa. 53:1-11, given the lexical connections between 52:15 and 53:1, as well as the seamlessness between the two verses.
