A prayer for Holy Week by Origen (c. 185–254):

Jesus, my feet are dirty. Come even as a slave to me, pour water into your bowl, come and wash my feet. In asking such a thing I know I am overbold, but I dread what was threatened when you said to me, “If I do not wash your feet I have no fellowship with you.” Wash my feet then, because I long for your companionship.
