'Testimony' in the Bible

while God corroborated their testimony by signs and marvels and various miracles, and by gifts of the Holy Spirit distributed in accordance with His own will.

And the Holy Spirit also gives us His testimony; for when He had said,

Any one who bids defiance to the Law of Moses is put to death without mercy on the testimony of two or three witnesses.

Through faith Abel offered to God a more acceptable sacrifice than Cain did, and through this faith he obtained testimony that he was righteous, God giving the testimony by accepting his gifts; and through it, though he is dead, he still speaks.
