John 13:12-17

Thomson(i) 12 So when he had washed their feet and put on his garments, having again taken his place at table, he said to them, Consider what I have done to you. 13 You call me The teacher and the master; and you say right, for so I am. 14 If I then, the master and the teacher, have washed your feet, you ought to wash one another's feet; 15 for I have set you an example, that you may do as I have done to you. 16 Verily, verily I say to you, The servant is not greater than his master; nor is a missionary greater than he who sent him. 17 If you know these things, happy are you if you practise them.
