This Jesus hath God raised up
That is, from the dead,
whereof we are all witnesses;
namely, of his resurrection, they having seen him, and heard him, and ate, and drank, and conversed with him since his resurrection; and which was true, not of the twelve apostles only, but of the whole company: or "we are all his witnesses"; either of God, who raised Christ from the dead; or of Christ who was raised by him; and indeed, they bore testimony to the whole of this, to Christ, and to his resurrection, and to its being done by God the Father.
