His father, Zacharias, was filled with the Holy Spirit, and prophesied, saying,
      (2.) He has wrought out redemption for them: He has redeemed his people. This was the errand on which Christ came into the world, to redeem those that were sold for sin, and sold under sin; even God's own people, his Israel, his son, his first-born, his free-born, need to be redeemed, and are undone if they be not. Christ redeems them by price out of the hands of God's justice, and redeems them by power out of the hands of Satan's tyranny, as Israel out of Egypt.
