John 13:3-17 New International Version
3 Jesus knew that the Father had put all things under his power, and that he had come from God and was returning to God;
4 so he got up from the meal, took off his outer clothing, and wrapped a towel around his waist.
5 After that, he poured water into a basin and began to wash his disciples’ feet, drying them with the towel that was wrapped around him.
6 He came to Simon Peter, who said to him, “Lord, are you going to wash my feet?”
7 Jesus replied, “You do not realize now what I am doing, but later you will understand.”
8 “No,” said Peter, “you shall never wash my feet.”
Jesus answered, “Unless I wash you, you have no part with me.”
9 “Then, Lord,” Simon Peter replied, “not just my feet but my hands and my head as well!”
10 Jesus answered, “Those who have had a bath need only to wash their feet; their whole body is clean. And you are clean, though not every one of you.”
11 For he knew who was going to betray him, and that was why he said not every one was clean.
12 When he had finished washing their feet, he put on his clothes and returned to his place. “Do you understand what I have done for you?” he asked them.
13 “You call me ‘Teacher’ and ‘Lord,’ and rightly so, for that is what I am.
14 Now that I, your Lord and Teacher, have washed your feet, you also should wash one another’s feet.
15 I have set you an example that you should do as I have done for you.
16 Very truly I tell you, no servant is greater than his master, nor is a messenger greater than the one who sent him.
17 Now that you know these things, you will be blessed if you do them.
Hebrews 13:1 New International Version
13 Keep on loving one another as brothers and sisters.
2 Peter 1:5-8 New International Version
5 For this very reason, make every effort to add to your faith goodness; and to goodness, knowledge;
6 and to knowledge, self-control; and to self-control, perseverance; and to perseverance, godliness;
7 and to godliness, mutual affection; and to mutual affection, love.
8 For if you possess these qualities in increasing measure, they will keep you from being ineffective and unproductive in your knowledge of our Lord Jesus Christ.
Revelation 2:3-5 New International Version
3 You have persevered and have endured hardships for my name, and have not grown weary.
4 Yet I hold this against you: You have forsaken the love you had at first.
5 Consider how far you have fallen! Repent and do the things you did at first. If you do not repent, I will come to you and remove your lampstand from its place.
