Judas Iscariot conspires with the Sanhedrin to betray Jesus.
Then one of the twelve, whose name was Judas Iscariot, went to the chief priests and said, “What will you give me if I deliver him over to you?” And they paid him thirty pieces of silver. And from that moment he sought an opportunity to betray him (Matthew 26:14-16).
