And killed the Prince of life, whom God hath raised from the dead; whereof we are witnesses. And killed the Prince of life - Τον αρχηγον της ζωης, The author of this life: not only implying that all life proceeds from Jesus Christ as its source, but that the life-giving influence of that religion which they were now proclaiming came all through him. Αρχηγος signifies a prime leader or author, a captain, from αρχη, the beginning, head, or chief; and αγω, I lead. In Hebrews 2:10, Christ is called Αρχηγος της σωτηριας, the Captain of salvation. He teaches the doctrine of life and salvation, leads the way in which men should walk, and has purchased the eternal life and glory which are to be enjoyed at the end of the way. So the Jews preferred a son of death, a destroyer of life, to the Author and Procurer of life and immortality!
Whereof we are witnesses - They had now wrought a most striking miracle in the name of Christ, and immediately proposed themselves as witnesses of his resurrection from the dead; the miracle which they had thus wrought being an unimpeachable proof of this resurrection.
