What does the Bible say about the betrayal of Jesus?

Judas Iscariot's betrayal is highlighted in passages such as John 13:18-30, where we see the devil put into his heart the intention to betray Jesus during the Last Supper. This event serves as a stark reminder of the profound truth that having knowledge of Christ and hearing His words is not sufficient for true faith. Judas heard the same truths as the other apostles but ultimately rejected them, demonstrating that understanding without a changed heart is perilous. Scripture warns us of this accountability, as stated in Matthew 10:14-15, emphasizing that those who hear the gospel have a higher responsibility to respond to it appropriately.
