John 13:12-20

So when He had washed their feet and put on His [outer] robe and reclined at the table again, He said to them, “Do you understand what I have done for you? You call Me Teacher and Lord, and you are right in doing so, for that is who I am. So if I, the Lord and the Teacher, washed your feet, you ought to wash one another’s feet as well. For I gave you [this as] an example, so that you should do [in turn] as I did to you. I assure you and most solemnly say to you, a slave is not greater than his master, nor is one who is sent greater than the one who sent him. If you know these things, you are blessed [happy and favored by God] if you put them into practice [and faithfully do them]. I am not speaking of all of you. I know whom I have chosen; but [this has happened] in order that the Scripture may be fulfilled: ‘HE WHO EATS MY BREAD HAS RAISED UP HIS HEEL AGAINST ME [as My enemy].’ [Ps 41:9] From now on I am telling you [what will happen] before it occurs, so that when it does take place you may believe that I am He [who I say I am—the Christ, the Anointed, the Messiah]. I assure you and most solemnly say to you, the one who receives and welcomes whomever I send receives Me; and the one who receives Me receives Him who sent Me [in that same way].”
