Commenting on Psalm 51:1-19
For I acknowledge my transgressions. Here he sees the plurality and immense number of his sins, and makes open declaration of them. He seems to say, I make a full confession of them. Not that this is my plea in seeking forgiveness, but it is a clear evidence that I need mercy, and am utterly unable to look to any other quarter for help.
The title has reference to a very sad story, that of David's fall. But, though he fell, he was not utterly cast down, for God graciously upheld him and raised him up. 1.
