 John 13:34-35
34 A new commandment I give to you, that you love one another; as I have loved you, that you also love one another. 35 By this all will know that you are My disciples, if you have love for one another.”

 Mark 14:12-16
12 Now on the first day of Unleavened Bread, when they sacrificed the Passover lamb, His disciples said to Him, “Where do You want us to go and prepare, that You may eat the Passover?”

13 And He sends two of His disciples and tells them, "Go into the city, and a man will meet you carrying a jar of water. Follow him.

14 Wherever he enters, say to the master of the house, ’The Teacher says, “Where is the guest room, in which I may eat the Passover with My disciples?” ’

15 And he will show you a large upper room furnished and ready. Prepare there for us."

16 So the disciples went out and went into the city and found it just as He had told them; and they prepared the Passover.

 John 13:1-11
1 Now before the Feast of the Passover, when Jesus knew that His hour had come that He should depart from this world to the Father, having loved His own who were in the world, He loved them to the end.

2 And supper being ended, the devil having already put it into the heart of Judas Iscariot, Simon’s son, to betray Him, 3 Jesus, knowing that the Father had given all things into His hands, and that He had come from God and was going to God, 4 rose from supper and laid aside His garments, took a towel and girded Himself. 5 After that, He poured water into a basin and began to wash the disciples’ feet, and to wipe them with the towel with which He was girded.

6 Then He came to Simon Peter. And Peter said to Him, “Lord, are You washing my feet?” 7 Jesus answered and said to him, “What I am doing you do not understand now, but you will know after this.” 8 Peter said to Him, “You shall never wash my feet!”

Jesus answered him, “If I do not wash you, you have no part with Me.”

9 Simon Peter said to Him, “Lord, not my feet only, but also my hands and my head!” 10 Jesus said to him, “He who is bathed needs only to wash his feet, but is completely clean; and you are clean, but not all of you.” 11 For He knew who would betray Him; therefore He said, “You are not all clean.”

 John 13:12-17
12 So when He had washed their feet, taken His garments, and sat down again, He said to them, “Do you know what I have done to you? 13 You call Me Teacher and Lord, and you say well, for so I am. 14 If I then, your Lord and Teacher, have washed your feet, you also ought to wash one another’s feet. 15 For I have given you an example, that you should do as I have done to you. 16 Most assuredly, I say to you, a servant is not greater than his master; nor is he who is sent greater than he who sent him. 17 If you know these things, blessed are you if you do them.

 Luke 22:14-18
14 When the hour had come, He sat down, and the twelve apostles with Him. 15 Then He said to them, “With fervent desire I have desired to eat this Passover with you before I suffer; 16 for I say to you, I will no longer eat of it until it is fulfilled in the kingdom of God.”

17 Then He took the cup, and gave thanks, and said, “Take this and divide it among yourselves; 18 for I say to you, I will not drink of the fruit of the vine until the kingdom of God comes.”

 Luke 22:19-23
19 And He took bread, gave thanks and broke it, and gave it to them, saying, “This is My body which is given for you; do this in remembrance of Me.”

20 Likewise He also took the cup after supper, saying, “This cup is the new covenant in My blood, which is shed for you. 21 But behold, the hand of My betrayer is with Me on the table. 22 And truly the Son of Man goes as it has been determined, but woe to that man by whom He is betrayed!”

23 Then they began to question among themselves, which of them it was who would do this thing.

 Mark 14:17-21
17 In the evening He came with the twelve. 18 Now as they sat and ate, Jesus said, “Assuredly, I say to you, one of you who eats with Me will betray Me.”

19 And they began to be sorrowful, and to say to Him one by one, “Is it I?” And another said, “Is it I?”

20 He answered and said to them, “It is one of the twelve, who dips with Me in the dish. 21 The Son of Man indeed goes just as it is written of Him, but woe to that man by whom the Son of Man is betrayed! It would have been good for that man if he had never been born.”

 John 13:21-30
21 When Jesus had said these things, He was troubled in spirit, and testified and said, “Most assuredly, I say to you, one of you will betray Me.” 22 Then the disciples looked at one another, perplexed about whom He spoke.

23 Now there was leaning on Jesus’ bosom one of His disciples, whom Jesus loved. 24 Simon Peter therefore motioned to him to ask who it was of whom He spoke. 25 Then, leaning back on Jesus’ breast, he said to Him, “Lord, who is it?”

26 Jesus answered, “It is he to whom I shall give a piece of bread when I have dipped it.” And having dipped the bread, He gave it to Judas Iscariot, the son of Simon. 27 Now after the piece of bread, Satan entered him. Then Jesus said to him, “What you do, do quickly.” 30 Having received the piece of bread, he then went out immediately. And it was night.

 John 13:33-35
33 Little children, I shall be with you a little while longer. You will seek Me; and as I said to the Jews, ‘Where I am going, you cannot come,’ so now I say to you. 34 A new commandment I give to you, that you love one another; as I have loved you, that you also love one another. 35 By this all will know that you are My disciples, if you have love for one another.”

 Luke 22:31-34
31 And the Lord said, “Simon, Simon! Indeed, Satan has asked for you, that he may sift you as wheat. 32 But I have prayed for you, that your faith should not fail; and when you have returned to Me, strengthen your brethren.”

33 But he said to Him, “Lord, I am ready to go with You, both to prison and to death.”

34 Then He said, “I tell you, Peter, the rooster shall not crow this day before you will deny three times that you know Me.”
