This is the disciple which beareth witness of these things, and wrote these things: and we know that his witness is true.
and ye also bear witness, because ye have been with me from the beginning.
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.
This is he that came by water and blood, even Jesus Christ; not with the water only, but with the water and with the blood.
Demetrius hath the witness of all men, and of the truth itself: yea, we also bear witness; and thou knowest that our witness is true.
