2 Samuel 7:19

And this, the wonderful external favors, was yet a small thing in Thy sight, O Lord God; but Thou hast spoken also of thy servant's house for a great while to come. And is this the manner of man, O Lord God? literally, "And this is the law of the man, namely, Lord Jehovah. " David not only understood that the Messianic prophecy was given to his family, that the eternal establishment of his house and kingdom, in the person of Messiah, was included in the prophecy which had come to him, but it was also clear to him that this singular descendant would, in His person, combine two natures, the human and the divine. Messiah, the true man, would at the same time be the Lord Jehovah.
