Of the fruit of his loins; such as should descend from him, as the virgin Mary did. According to the flesh; as to his human nature, which our Saviour did truly partake of, being in the form of a servant. He would raise up Christ, by the power of the Holy Ghost in the womb of his virgin mother, as to his incarnation; and by the same power out of the grave, in his resurrection. To sit on his throne; as Luke 1:32,33: not as a temporal king, for his kingdom is not of this world; but as David ruled over all the people of God, so does Christ, and shall do for ever.
