What does the Bible say about Jesus' suffering on the cross?

According to the Scriptures, particularly Isaiah 53, Jesus endured unparalleled suffering during His crucifixion, which went beyond physical pain to the agony of bearing the sins of His people. He was wounded for our transgressions and crushed for our iniquities, facing not only the harsh realities of crucifixion but also the weight of divine judgment for sin. His declaration 'It is finished' signifies the completion of His suffering and sacrificial work, whereby He perfectly fulfilled the law's demands and bore the full penalty for sin.
