11 For He knew who was going to betray Him; that was the reason He said, Not all of you are clean.
12 So when He had finished washing their feet and had put on His garments and had sat down again, He said to them, Do you understand what I have done to you?
13 You call Me the Teacher (Master) and the Lord, and you are right in doing so, for that is what I am.
14 If I then, your Lord and Teacher (Master), have washed your feet, you ought [it is your duty, you are under obligation, you owe it] to wash one another's feet.
15 For I have given you this as an example, so that you should do [in your turn] what I have done to you.
16 I assure you, most solemnly I tell you, A servant is not greater than his master, and no one who is sent is superior to the one who sent him.
17 If you know these things, blessed and happy and to be envied are you if you practice them [if you act accordingly and really do them].
