The washing of the feet on Maundy Thursday commemorates Jesus washing the feet of his disciples at the Last Supper. According to the Bible, Jesus instructed his disciples that they should wash one another's feet, just as he had done for them. Many Christian churches continue this tradition during Holy Week as part of their worship services, based on Jesus' command to serve others humbly. Historically, foot washing was a common act of hospitality in many ancient civilizations, given that sandals were the main form of footwear and feet became dusty and dirty from walking.
