A 9th century Judaic text says: "During the seven-year period preceding the coming of the son of David, iron beams will be brought low and loaded upon his neck until the Messiah's body is bent low. Then he will cry and weep, and his voice will rise to the very height of heaven, and he will say to God: Master of the universe, how much can my strength endure? How much can my spirit endure? How much my breath before it ceases? How much can my limbs suffer? Am I not flesh and blood? It was because of the ordeal of the son of David that David wept, saying My strength is dried up like a potsherd (Ps. 22:16). During the ordeal of the son of David, the Holy One, blessed be He, will say to him: Ephraim, My true Messiah, long ago, ever since the six days of creation, thou didst take this ordeal upon thyself. At this moment, thy pain is like my pain . . . At these words, the Messiah will reply: Now I am reconciled. The servant is content to be like his Master."
