John Calvin Commentary Psalms 25:17

"The troubles of my heart are enlarged: Oh bring thou me out of my distresses." — Psalms 25:17 (ASV)

The troubles of my heart are enlarged. In this verse he acknowledges not only that he had to contend outwardly with his enemies and the troubles they caused him, but that he was also afflicted inwardly with sorrow and anguish of heart. It is also necessary to observe the manner of expression he uses here, by which he suggests that the weight and number of his trials had accumulated to such an extent that they filled his whole heart, just as a flood of waters, bursting every barrier and extending far and wide, covers a whole country. Now, when we see that David's heart had sometimes been wholly filled with anguish, we need no longer wonder if at times the violence of temptation overwhelms us; but let us ask with David that, even while we are, as it were, at the point of despair, God would help us.
