King James Bible
"Jesus saith to him, He that is washed needeth not save to wash his feet, but is clean every whit: and ye are clean, but not all."
Jesus distinguishes between complete bathing and partial washing, reflecting the custom of foot-washing after walking dusty roads. The metaphor suggests that those who have received spiritual cleansing through faith need only address daily sins, not undergo complete re-conversion. This emphasizes the completeness of the initial cleansing—the believer's fundamental spiritual status remains pure despite minor daily defilements. The phrase underscores the permanence and thoroughness of salvation. Jesus affirms the disciples' spiritual cleanliness while making a dark exception, alluding to Judas who would betray him. This contrast between the eleven faithful disciples and the one traitor foreshadows the imminent betrayal and highlights that external association with Jesus doesn't guarantee internal purity.
