John 13:10-12

King James Version

¹⁰ 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.

¹¹ For he knew who should betray him; therefore said he, Ye are not all clean.

¹² So after he had washed their feet, and had taken his garments, and was set down again, he said unto them, Know ye what I have done to you?
