Psalm 5

How did David learn that his God despises wrong-doing? That he is not pleased by those who are wicked? Such truths would be difficult to discern from trial and error or observation of other people. Surely these were the words that Jesse taught from the Law, or that David had heard from Samuel as he traveled through the area. I wonder how many lives were lived out before David to re-enforce this truthful teaching? Did David catch a picture of God's graciousness as he with-held his immediate judgment from the guilty?
