What does the Bible say about the suffering of the Son of Man?

The suffering of the Son of Man is central to the Redeemer's mission, as outlined in Luke 9:22, where it states that He must suffer, be rejected, be slain, and be raised on the third day. This suffering includes not only physical agony but also spiritual separation from the Father, a concept emphasized in passages like Psalm 22, where it describes His anguish. Christ’s suffering is an intrinsic part of the covenant of grace, fulfilling the prophecies foretold in Scripture about the Messiah's necessary suffering for the salvation of His people.
