G0584–ἀποδείκνυμι–apodeiknumi

Ye men of Israel, hear these words; Jesus of Nazareth, a man approved by God among you by miracles and wonders and signs, which God did by him in the midst of you, as ye yourselves also know:

ἀποδεδειγμένον apodedeigmenon “set forth”

And when he had come, the Jews who came down from Jerusalem stood around, and laid many and grievous complaints against Paul, which they could not prove;

ἀποδεῖξαι, apodeixai “to prove,”

For I think that God hath set forth us the apostles last, as it were appointed to death: for we are made a spectacle to the world, and to angels, and to men.

ἀπέδειξεν apedeixen “has exhibited”

Who opposeth and exalteth himself above all that is called God, or that is worshiped; so that he as God sitteth in the temple of God, showing himself that he is God.
