15:1-24 Wise and good men may be guilty of oversights, which they will correct, as soon as they are aware of them. David does not try to justify what had been done amiss, nor to lay the blame on others; but he owns himself guilty, with others, of not seeking God in due order

15:25-29 It is good to notice the assistance of Divine Providence, even in things which fall within the compass of our natural powers; if God did not help us, we could not stir a step. If we do our religious duties in any degree aright, we must own it was God that helped us; had we been left to ourselves, we should have been guilty of some fatal errors. And every thing in which we engage, must be done in dependence on the mercy of God through the sacrifice of the Redeemer.
