John 13:12 WEB

¹⁰  Jesus said to him, 'Someone who has bathed only needs to have his feet washed, but is completely clean. You are clean, but not all of you.'

¹¹  For he knew him who would betray him, therefore he said, 'You are not all clean.'

¹²  So when he had washed their feet, put his outer garment back on, and sat down again, he said to them, 'Do you know what I have done to you?

¹³  You call me, 'Teacher' and 'Lord.' You say so correctly, for so I am.

¹⁴  If I then, the Lord and the Teacher, have washed your feet, you also ought to wash one another's feet.
