As he spake to our fathers,.... To David, of whose family Mary was; and to Jacob, or Israel, of whose stock she was; and to Isaac, in whom the seed was to be, called; and particularly, to Abraham and to his seed for ever: not his natural, but his spiritual seed; both among Jews and Gentiles, to the end of the world; to these God promised this mercy of a Saviour and Redeemer, and to these he performs it, and will to all generations.
