There are two notable occasions when feet were washed in the Easter story. The first occurred in Bethany, when Jesus was eating at the house of Simon the Leper. A woman – often supposed to be Mary Magdalene (Letter M) – arrived and anointed Jesus’ feet with expensive perfume. Then she washed his feet with her tears and dried them with her hair. John 12:1-3 and Luke 7:37-5 As the custom of the time was not to sit upright at a table, but to recline on a couch at the side or end of a table, the people’s feet would be easily reached by anyone approaching the table.
When people arrived for a meal in someone’s house it was customary for a servant to wash their feet. At the Passover meal (Letter L) in the upper room (Letter U). Jesus washed the feet of his disciples, demonstrating that although he was a king (Letter K), he had come to earth as a servant
In some church services on Maundy Thursday there is still a foot-washing ceremony.
