Final answer:
The Old Testament prophet's book that contains a detailed prophecy of the Messiah's crucifixion is Isaiah 53, which describes the suffering and sacrificial death of a servant figure that Christians interpret as Jesus Christ.
Step-by-step explanation:
The detailed prophecy of the Messiah's death by crucifixion in an Old Testament prophet's book is found in Isaiah 53. This chapter, often referred to as the 'Suffering Servant' passage, portrays a servant who suffers and bears the sins of others. It is interpreted by Christians as a clear prediction of Jesus Christ's sufferings and death on the cross. Isaiah's vivid descriptions of the servant's trials and eventual sacrifice have long been seen by believers as foreshadowing Christ's crucifixion and the redemptive purpose it served.
The Messiah's death on the cross is central to Christian theology and is represented in various forms of art and literature. In Isaiah 53, phrases such as "He was pierced for our transgressions" and "the Lord has laid on Him the iniquity of us all" are seen as direct foretelling's of the events that would take place centuries later during the Crucifixion of Jesus.
