»Give not that which is holy to the dogs, nor throw your pearls to the swine; otherwise they will trample them under their feet and then turn and attack you.«
My meaning is that Christ has become a servant to the people of Israel in vindication of God's truthfulness –in showing how sure are the promises made to our forefathers–
At that time you were living apart from Christ, estranged from the Commonwealth of Israel, with no share by birth in the Covenants which are based on the Promises, and you had no hope and no God, in all the world.
