'Testifieth' in the Bible

And what he hath seen and heard, that he testifieth; and no man receiveth his testimony.

This is the disciple which testifieth of these things, and wrote these things: and we know that his testimony is true.

For he testifieth, Thou art a priest for ever after the order of Melchisedec.

He which testifieth these things saith, Surely I come quickly. Amen. Even so, come, Lord Jesus.
