Isaiah 53 has nothing to do with Jesus. I fail to see its relevancy. You must not forget that the OT is basically the Torah. As we know that the orthodox Jews were unimpressed at all times by Jesus, Isaiah 53 must refer to events of Jewish concern.
Notice how in Isa 53:7 it says "He was oppressed, and he was afflicted, yet he opened not his mouth: he is brought as a lamb to the slaughter, and as a sheep before her shearers is dumb, so he openeth not his mouth." All in the past tense.
For a prophecy, you would expect
Isa 53:7 He will be oppressed, and he will be afflicted, yet he will not his mouth: he will be brought as a lamb to the slaughter, and as a sheep before her shearers is dumb, so he will open not his mouth.
This is what they call "Quote Mining" you find something you want to prove and then you go looking for the evidence to support it. Once it is found, everything else is dismissed and you claim it as proof without relating it to anything that went before or after.
This is a typically Christian way of dispensing with logic and fooling the gullible.
I don't expect you will, but you should look at some Jewish sources for the context and meaning of Isa:53, it's quite interesting.
