2 Samuel 7:21

For thy word's sake; In 1 Chronicles 17:19 we read, "For thy servant's sake." The phrase seemed, perhaps, to the Chronicler difficult, but it does not mean "because of thy previous promise," for no such promise had been given, but "because thou hast now said it." Nor does it imply pre-existing merit in David, but that God had now chosen to declare his will, and what was according to his own heart. It thus makes God's own good will and pleasure the cause of the great honours bestowed upon David. Instead of these great things, the Hebrew has this great thing; that is, the lasting continuance of David's family.
