1 Chronicles 28:7

Moreover, I will establish his kingdom for ever
The same is said in ( 2 Samuel 7:13 )

if he be constant to do my commandments, and my judgments, as at this
day;
if he continued in the observance of them, as he had begun, and went on in until that day; this is added here, and was not spoken by Nathan, when what goes before was; for Solomon was not then born, but must be suggested to David since, and as it should seem at this time.
