Matthew

26:31 Then saith Jesus unto them, All ye shall be offended because of me this night: for it is written, I will smite the shepherd, and the sheep of the flock shall be scattered abroad.
32 But after I am risen again, I will go before you into Galilee.
33 Peter answered and said unto him, Though all men shall be offended because of thee, yet will I never be offended.
34 Jesus said unto him, Verily I say unto thee, That this night, before the cock crow, thou shalt deny me thrice.
35 Peter said unto him, Though I should die with thee, yet will I not deny thee. Likewise also said all the disciples.
69 Now Peter sat without in the palace: and a damsel came unto him, saying, Thou also wast with Jesus of Galilee.
70 But he denied before them all, saying, I know not what thou sayest.
71 And when he was gone out into the porch, another maid saw him, and said unto them that were there, This fellow was also with Jesus of Nazareth.
72 And again he denied with an oath, I do not know the man.
73 And after a while came unto him they that stood by, and said to Peter, Surely thou also art one of them; for thy speech bewrayeth thee.
74 Then began he to curse and to swear, saying, I know not the man. And immediately the cock crew.
75 And Peter remembered the word of Jesus, which said unto him, Before the cock crow, thou shalt deny me thrice. And he went out, and wept bitterly.

Romans

12:3 For I say, through the grace given unto me, to every man that is among you, not to think of himself more highly than he ought to think; but to think soberly, according as God hath dealt to every man the measure of faith.

John

21:1 After these things Jesus shewed himself again to the disciples at the sea of Tiberias; and on this wise shewed he himself.
2 There were together Simon Peter, and Thomas called Didymus, and Nathanael of Cana in Galilee, and the sons of Zebedee, and two other of his disciples.
3 Simon Peter saith unto them, I go a fishing. They say unto him, We also go with thee. They went forth, and entered into a ship immediately; and that night they caught nothing.
4 But when the morning was now come, Jesus stood on the shore: but the disciples knew not that it was Jesus.
5 Then Jesus saith unto them, Children, have ye any meat? They answered him, No.
6 And he said unto them, Cast the net on the right side of the ship, and ye shall find. They cast therefore, and now they were not able to draw it for the multitude of fishes.
7 Therefore that disciple whom Jesus loved saith unto Peter, It is the Lord. Now when Simon Peter heard that it was the Lord, he girt his fisher's coat unto him, (for he was naked,) and did cast himself into the sea.
8 And the other disciples came in a little ship; (for they were not far from land, but as it were two hundred cubits,) dragging the net with fishes.
9 As soon then as they were come to land, they saw a fire of coals there, and fish laid thereon, and bread.
10 Jesus saith unto them, Bring of the fish which ye have now caught.
11 Simon Peter went up, and drew the net to land full of great fishes, an hundred and fifty and three: and for all there were so many, yet was not the net broken.
12 Jesus saith unto them, Come and dine. And none of the disciples durst ask him, Who art thou? knowing that it was the Lord.
13 Jesus then cometh, and taketh bread, and giveth them, and fish likewise.
14 This is now the third time that Jesus shewed himself to his disciples, after that he was risen from the dead.
15 So when they had dined, Jesus saith to Simon Peter, Simon, son of Jonas, lovest thou me more than these? He saith unto him, Yea, Lord; thou knowest that I love thee. He saith unto him, Feed my lambs.
16 He saith to him again the second time, Simon, son of Jonas, lovest thou me? He saith unto him, Yea, Lord; thou knowest that I love thee. He saith unto him, Feed my sheep.
17 He saith unto him the third time, Simon, son of Jonas, lovest thou me? Peter was grieved because he said unto him the third time, Lovest thou me? And he said unto him, Lord, thou knowest all things; thou knowest that I love thee. Jesus saith unto him, Feed my sheep.
18 Verily, verily, I say unto thee, When thou wast young, thou girdedst thyself, and walkedst whither thou wouldest: but when thou shalt be old, thou shalt stretch forth thy hands, and another shall gird thee, and carry thee whither thou wouldest not.
19 This spake he, signifying by what death he should glorify God. And when he had spoken this, he saith unto him, Follow me.
