David describes the guilt of sin as a heavy burden. He feels “feeble and crushed”, spending his day mourning, distanced from friends and companions, ready to fall.
In this state he knows all he can do is turn to God. “But for you, O Lord, do I wait; it is you, O Lord my God, who will answer”. He confesses his sin, and pleads with God not to forsake him, a vivid example of the need to take refuge in God, our stronghold in time of trouble.
