John 8:16 YLT

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.'
