'Borne Witness' in the Bible

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

And they came to John, and said to him, Rabbi, he who was with thee beyond the Jordan, to whom thou hast borne witness, behold, he baptizeth, and all men are going to him.

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

And the Father who 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 what is true, that ye also may believe.
