Jesus and his disciples were gathered in Jerusalem to celebrate the Passover. Jesus knew that he was about to die, and that Judas would betray him. He decided to show his love to his friends (even Judas) by washing their feet, which was normally the job of a slave or servant, to make them clean before they shared the Last Supper together. Peter was bothered by Jesus acting like a slave, but Jesus said that no master is better than his servant, and that the disciples should follow his example of humility and service.
