John 13:10-17 New Revised Standard Version (NRSV)
10 Jesus said to him, “One who has bathed does not need to wash, except for the feet,[a] but is entirely clean. And you[b] are clean, though not all of you.” 11 For he knew who was to betray him; for this reason he said, “Not all of you are clean.”
12 After he had washed their feet, had put on his robe, and had returned to the table, he said to them, “Do you know what I have done to you? 13 You call me Teacher and Lord—and you are right, for that is what I am. 14 So if I, your Lord and Teacher, have washed your feet, you also ought to wash one another’s feet. 15 For I have set you an example, that you also should do as I have done to you. 16 Very truly, I tell you, servants[c] are not greater than their master, nor are messengers greater than the one who sent them. 17 If you know these things, you are blessed if you do them.
John 13:31-35 New Revised Standard Version (NRSV)
The New Commandment
31 When he had gone out, Jesus said, “Now the Son of Man has been glorified, and God has been glorified in him. 32 If God has been glorified in him,[a] God will also glorify him in himself and will glorify him at once. 33 Little children, I am with you only a little longer. You will look for me; and as I said to the Jews so now I say to you, ‘Where I am going, you cannot come.’ 34 I give you a new commandment, that you love one another. Just as I have loved you, you also should love one another. 35 By this everyone will know that you are my disciples, if you have love for one another.”
