Jesus told his disciples about mutual love and service. He represented a model of humility and meekness before them, and foretold that his sovereignty would shine forth amid weakness, so that they might be aware that he is Lord, the doer and director of events, even in the hour of death. As part of this clarification, Jesus exposed Judas’ treachery and conceded him the perpetration of his crime, in order that Judas might not act according to his private plot only, but in line with the oversight of heaven.
Jesus disclosed to his disciples that one of them had decided to deliver him to the Council of Jewry. This announcement came as an explosive during a happy festival. Jesus did not announce this fact casually, but was himself troubled in Spirit, as he had been at the grave of Lazarus. He was grieving especially at the thought that his Father would leave him. Jesus had loved Judas and chosen him; it seemed impossible that a chosen friend would betray the Son of God. Although the Bible refers to this in Psalm 41:9, "He who eats my bread has lifted his heel against me."
At that, the disciples scanned each his colleague thinking, "Is he the traitor?" They had misgivings about whether it was possible for any to intend betrayal. Each had in mind the thought of leaving Jesus as soon as his way would take a downward trend in scorn and rejection. They saw themselves exposed before him, were ashamed and were unable to face the divine test before the searching light of Jesus.
