John 13:33-38

33 `Little children, yet a little am I with you; ye will seek me, and, according as I said to the Jews -- Whither I go away, ye are not able to come, to you also I do say [it] now.

34 `A new commandment I give to you, that ye love one another; according as I did love you, that ye also love one another;

35 in this shall all know that ye are my disciples, if ye may have love one to another.'

36 Simon Peter saith to him, `Sir, whither dost thou go away?' Jesus answered him, `Whither I go away, thou art not able now to follow me, but afterward thou shalt follow me.'

37 Peter saith to him, `Sir, wherefore am I not able to follow thee now? my life for thee I will lay down;'

38 Jesus answered him, `Thy life for me thou wilt lay down! verily, verily, I say to thee, a cock will not crow till thou mayest deny me thrice.'
