Another expression that has Biblical origins, to wash feet is sometimes used on channel (by Number-6, among others) as a euphemism for sexual relations. The Biblical references to feet-washing are many and varied, but it is sometimes interpreted as having sexual overtones. Interestingly, the sexual overtones are only interpreted when women -- most prominently, Mary Magdalene in Luke 7 -- are doing the foot-washing and not when Jesus is doing the foot-washing, as in John 13. Even as far back as the story of the destruction of Sodom and Gomorrah (see: to know), there are references to foot-washing (Genesis 19:2).The reference most people have in mind when they use feet-washing as a sexual euphemism is Mary Magdalene's washing of Jesus' feet with her tears of devotion in Luke 7:44-50. Commonly (though without Biblical substantiation) identified as a prostitute by the Roman Catholic Church, there is much debate over the accuracy of the depiction of Mary Magdalene, to whom Christ chooses to first appear after His resurrection (Mark 16:9-11).
