John 13:12-14

New Catholic Bible

¹²After he had finished washing their feet and had once again put on his outer garments, he reclined at table and said to them,

“Do you understand
what I have done for you?
¹³You call me ‘Teacher’ and ‘Lord,’
and rightly so,
for that is what I am.
¹⁴So if I, your Lord and Teacher,
have washed your feet,
you also should wash one another’s feet.
