"Moses gave the Law but couldn't fulfill it. Joshua perpetuated the Law (Joshua 1:8) but couldn't satisfy it's demands. King David loved the Law (Psalm 119:163) but broke it. The prophets upheld the Law but couldn't keep it as required. The Levites carried out the Law but still came short of it. The Pharisees and Sadducees and teachers of the Law argued about it but did not have a clue as to it's deeper meaning".
