Psalm 6.  David is suffering between a rock (apparently an illness from which he needs healing (2)) and a hard place (his enemies gloating over his misfortune).  He does not want to die for two reasons. First, the state of death (Sheol) offers no opportunity for a worship or a conscious relationship with God (5). Second, his enemies would have even more reason to gloat at his defeat. He prays that the LORD would deliver his life (4) for the sake of his steadfast love. By the end of his prayer he is confident that God has accepted his plea, and that his enemies will have to retreat. He knows God is going to intervene.

LORD, when we are between a rock and a hard place, remind us to pray. You can change things.
