And is this the manner of man - Literally: And this, O Lord God, is the law of Adam. Does he refer to the promise made to Adam, The seed of the woman shall bruise the head of the serpent? From my line shall the Messiah spring, and be the spiritual and triumphant King, for ever and ever. See the additions at the end, 2 Samuel 7:25; (note).
Is this the manner of man - Compare 1 Chronicles 17:17. Our passage may be thus understood: But this is the law (or prerogative) of a great man to found dynasties which are to last into the far future. David expresses his astonishment that he, of such humble birth, and one so little in his own eyes, should not only be raised to the throne, but be assured of the perpetuity of the succession in his descendants, as if he were a man of high degree.
