acts 2:36 Therefore let all the house of Israel know assuredly, that God hath made that same Jesus, whom ye have crucified, both Lord and Christ. - Free Bible Online

      36. Therefore--that is, to sum up all.
      let all the house of Israel--for in this first discourse the appeal is formally made to the whole house of Israel, as the then existing Kingdom of God.
      know assuredly--by indisputable facts, fulfilled predictions, and the seal of the Holy Ghost set upon all.
      that God hath made--for Peter's object was to show them that, instead of interfering with the arrangements of the God of Israel, these events were His own high movements.
      this same Jesus, whom ye have crucified--"The sting is at the close" [BENGEL]. To prove to them merely that Jesus was the Messiah might have left them all unchanged in heart. But to convince them that He whom they had crucified had been by the right hand of God exalted, and constituted the "LORD" whom David in spirit adored, to whom every knee shall bow, and the CHRIST of God, was to bring them to "look on Him whom they had pierced and mourn for Him."
