Psalm 51 was written by King Davidafter he committed adulterywith Bathsheba and had her husband killed to cover his sin (2 Samuel 11). It has been said of David that he sinned big, but repented bigger. He is a model to us of what real heart repentance looks like. He wrote this psalm as an agonized cry to God for forgiveness.... What do u understand by What does it mean "that God will not despise a broken spirit and contrite heart"
