Psalm 5 begins with a straightforward request: "O Lord, hear me as I pray; pay attention to my groaning" (v. 1). The psalmist, King David, was in a gloomy place. We don't know his situation, but David was experiencing some measure of loss, sorrow or torment. He was in pain, "groaning". And in his difficult place, David wanted God to hear his agony. He needed God to listen to his "cry for help" (v. 2).
David didn't run to his advisers or his wife or the many wise sages of his court for aid. None of them could help him. He didn't roll up his sleeves and pore over documents, figuring out some solution to his predicament. David knew he couldn't help himself. He went directly to the only One who could meet him in his darkness.
"I pray to no one but You", David said (v. 2). David waited, watching for God. David's only work was not to work. He decided to bring his heart and his hope to God and then to "wait expectantly" (v. 3).
