In jambon1's thread http://www.jehovahs-witness.com/6/128929/1.ashx I suggested the possibility that Jesus was not required by Scripture, nor necessarily described in Scripture, as "suffering" in the physical sense of bodily pain.
I specifically had in mind Hebrews 2:18: "...he himself has suffered..." The Greek word used here is pascho, which has a general meaning of "to be affected by a thing, whether good or bad." Thus, in the compound form sympatheo (whence the English 'sympathy'), the sense is "compassion, fellow-feeling." This word is subsequently used in regard to Jesus in Hebrews 4:15: "...not one who cannot sympathize with our weaknesses..." Again, the word "weaknesses" (Greek astheneia) means simply "without strength," and does not necessarily include the thought of physical pain.
In Isaiah 53:4 it is said that "He...is pained for us..." (LXX), and the Greek word is odunao, meaning "pain of body or mind; sorrow, grief," and is also used in a 'positive' sense in the Scriptures (positive in the sense that physical pain is not necessarily included as an aspect of the experience).
This is an admittedly a limited initial examination, but if the postulate holds, then it would present a somewhat different perspective about Jesus than I previously held.
