Acts 3:15

the Prince of life The same word applied to Jesus (Hebrews 12:2) is rendered "authorand finisher of our faith," and in the same epistle (Acts 2:10) "the captainof their salvation." It is probably in the latter sense that St Peter, whose thoughts are on the Resurrection, uses the word here, thinking of Christ as the firstfruits of them that slept (1 Corinthians 15:20), but the other sense, that "in him was life" (John 1:4), is also embraced in the word.

whom God hath raised Better, whom God raised, i.e. once for all.

whereof we are witnesses The relative is here better referred to Christ, "of whomwe are witnesses." Not merely did they bear witness of the Resurrection, though that was a most important portion of their testimony, but of all Christ's teaching and deeds. Cp. Acts 1:22, where Matthias was chosen to be such a witness.
