John 13:9-11 NIV

[9] “Then, Lord,” Simon Peter replied, “not just my feet but my hands and my head as well!” [10] Jesus answered, “Those who have had a bath need only to wash their feet; their whole body is clean. And you are clean, though not every one of you.” [11] For he knew who was going to betray him, and that was why he said not every one was clean.
