John 13:31-38

31 When he therefore was gone out, Jesus said: Now is the Son of man glorified; and God is glorified in him.

32 If God be glorified in him, God also will glorify him in himself: and immediately will he glorify him.

33 Little children, yet a little while I am with you. You shall seek me. And as I said to the Jews: Whither I go you cannot come; so I say to you now.

34 A new commandment I give unto you: That you love one another, as I have loved you, that you also love one another.

35 By this shall all men know that you are my disciples, if you have love one for another.

36 Simon Peter saith to him: Lord, whither goest thou? Jesus answered: Whither I go, thou canst not follow me now: but thou shalt follow hereafter.

37 Peter saith to him: Why cannot I follow thee now? I will lay down my life for thee.

38 Jesus answered him: Wilt thou lay down thy life for me? Amen, amen, I say to thee, the cock shall not crow, till thou deny me thrice.
