'Bears Witness' in the Bible

(John bears witness of him, and he has cried, saying, This was he of whom I said, He that comes after me is preferred before me, for he was before me;)

What He has seen and heard, to that He bears witness; but His testimony no one receives.

It is another who bears witness concerning me, and I know that the witness which he bears concerning me is true.

I am one who bear witness concerning myself, and the Father who has sent me bears witness concerning me.

And he who saw it bears witness, and his witness is true, and he knows that he says true that ye also may believe.

This is the disciple who bears witness concerning these things, and who has written these things; and we know that his witness is true.
