'Bear Witness' in the Bible

This one came as a witness, to bear witness concerning the Light, so that all might believe through him.

He was not that Light, but was sent to bear witness of that Light.

You yourselves bear witness to me that I said, I am not the Christ, but that I am sent before Him.

If I bear witness of Myself, My witness is not true.

Jesus answered them, I told you and you did not believe. The works that I do in My Father's name, they bear witness of Me.

And you also shall bear witness, because you have been with Me from the beginning.

Jesus answered him, If I have spoken evil, bear witness of the evil; but if well, why do you strike Me?

Pilate then said to Him, Are you a king then? Jesus answered, You say it that I am a king. To this end I was born, and for this cause I came into the world, that I should bear witness to the truth. Everyone who is of the truth hears My voice.
