At the Last Supper, as recorded in John 13:1-17, Jesus washed the disciples' feet. Before the Passover meal, Jesus rose from the table, removed His outer garment, wrapped a towel around His waist, poured water into a basin, and began washing and drying the disciples' feet. When Peter objected, Jesus told him, "Unless I wash you, you have no part with me" (John 13:8).
This act was remarkable because foot-washing was normally the task of the lowest household servant. By performing it Himself, Jesus demonstrated radical humility and servant leadership. After washing their feet, He said, "I have set you an example that you should do as I have done for you" (John 13:15), teaching that greatness in God's kingdom is measured by willingness to serve others.
The other options describe events from different occasions. Jesus multiplied food (the feeding of the five thousand) during His Galilean ministry, not at the Last Supper. He drove out money changers from the temple during the cleansing of the temple. The Ten Commandments were given through Moses at Mount Sinai, centuries before Jesus' ministry.
