What does the Bible say about Jesus' predictions of his death?

In Matthew 17:22-23, Jesus foretells his betrayal, death, and resurrection, a theme He repeats in Matthew 16:21 and Matthew 20:18-19. This repetition highlights the gravity of his impending sacrifice for the sins of humanity. The disciples, despite hearing these predictions multiple times, struggled to grasp the concept that their Messiah would die. This inability signifies the deep misconceptions they had about the nature of Jesus' mission, focusing primarily on political liberation rather than spiritual salvation.
