'Washed My Feet' in the Bible

I have put off my coat; how shall I put it on? I have washed my feet; how shall I defile them?

And he turned to the woman, and said unto Simon, Seest thou this woman? I entered into thine house, thou gavest me no water for my feet: but she hath washed my feet with tears, and wiped them with the hairs of her head.
