John 8:14-24

14 Jesus answered and said to them, `And if I testify of myself -- my testimony is true, because I have known whence I came, and whither I go, and ye -- ye have not known whence I come, or whither I go.
15 `Ye according to the flesh do judge; I do not judge any one,
16 and even if I do judge my judgment is true, because I am not alone, but I and the Father who sent me;
17 and also in your law it hath been written, that the testimony of two men are true;
18 I am [one] who is testifying of myself, and the Father who sent me doth testify of me.'
19 They said, therefore, to him, `Where is thy father?' Jesus answered, `Ye have neither known me nor my Father: if me ye had known, my Father also ye had known.'
20 These sayings spake Jesus in the treasury, teaching in the temple, and no one seized him, because his hour had not yet come;
21 therefore said Jesus again to them, `I go away, and ye will seek me, and in your sin ye shall die; whither I go away, ye are not able to come.'
22 The Jews, therefore, said, `Will he kill himself, because he saith, Whither I go away, ye are not able to come?'
23 and he said to them, `Ye are from beneath, I am from above; ye are of this world, I am not of this world;
24 I said, therefore, to you, that ye shall die in your sins, for if ye may not believe that I am [he], ye shall die in your sins.'
