The second half of the Bible book "Isaiah," from Chapter Forty to Chapter Sixty-sixth is known as Dutero Isaiah. Imbedded within it are a number of hymns to the Suffering Servant. They can refer to pious Israelites, however Jesus himself identified with them. Let me quote from three of them.
Chapter 42 "Here is my servant whom I uphold. He shall bring forth justice to the nations , not crying out, not shouting, not making his voice heard in the street."
Chapter 49 "You are my servant, he said to me. t hough I thought I had toiled in vain, yet my reward is with the Lord."
Chapter 53 "He was spurned, and avoided by men; a man of suffering, accustomed to infirmity. One of those from whom men hide their faces."
