'Borne Witness' in the Bible

And I have seen, and have borne witness that this is the Son of God.

And they came unto John, and said to him, Rabbi, he that was with thee beyond the Jordan, to whom thou hast borne witness, behold, the same baptizeth, and all men come to him.

Ye have sent unto John, and he hath borne witness unto the truth.

And the Father that sent me, he hath borne witness of me. Ye have neither heard his voice at any time, nor seen his form.

And he that hath seen hath borne witness, and his witness is true: and he knoweth that he saith true, that ye also may believe.
