Why is the Cross of Jesus considered as a stumbling block for the Jews?

The Cross of Jesus is considered a stumbling block for the Jews because it challenges their expectations of a Messiah who would deliver them politically and restore their national sovereignty. Instead, Jesus' crucifixion represents a form of humiliation and defeat, conflicting with their beliefs about divine power and salvation. Additionally, the concept of a crucified Messiah contradicts the Jewish understanding of God's promise and the nature of redemption, leading to skepticism and rejection among many Jewish leaders and followers.
