Are you really basing doctrine on a poetic device? The context of that poem makes it clear that 53:2 is hyperbole especially since immediately after it references God's people in contrast to the wicked it is speaking of in 53:1-4. It really shows poor exegetical skills when you treat every bit of Biblical literature as if it is the same type of literature. Recognizing the genre and the types of devices employed within that genre are critical to getting an accurate understanding.
