Isaiah 53

It took me 2 minutes to read this chapter. The message of the suffering servant began in 52:13 and carries through chapter 53. I wonder how God revealed this to Isaiah? Was it in a vision where Isaiah witnessed the beating, abuse, and crucifixtion? Did God give his prophet the viewpoint of Caiphas? Did God speak this poem of suffering and leave the imagry to Isaiah's imagination? Was Isaiah an eyewitness to one of Manasseh's rigged trials and as the victim'sbody was carried away God explained how his Messiah would suffer in a similar man? The biggest question I have is this: did Isaiah cry as he wrote these words? Surely the prophet realized that this death centuries in the future would make peremant the forgiveness the animal sacrifice.
