'Who Testifies' in the Bible

There is someone else who testifies to me, and I know that the testimony which He gives to me is of force.

This is the disciple who testifies to these things and who wrote them down, and we know that his testimony is true.

who testifies to what he saw, the message of God and the testimony of Jesus Christ.

He who testifies to this says, "Yes, I am coming soon!" Amen! Come, Lord Jesus!
