The "Betrayal of Jesus" refers to the event in the New Testament where one of Jesus' disciples, Judas Iscariot, betrays him for thirty pieces of silver. This act leads to Jesus' arrest by the religious authorities in Jerusalem. Judas identifies Jesus by giving him a kiss, which allows the soldiers to apprehend him. This betrayal is significant in Christian theology as it sets in motion the events leading to the crucifixion of Jesus. It highlights themes of loyalty and treachery, and it fulfills prophecies found in the Hebrew Scriptures. Judas later regrets his actions and returns the silver, ultimately leading to his demise.
