The Bible makes no attempt to minimize the extent to which David fell into great sin. At a minimum, he was guilty of adultery and murder in the episode with Bathsheba (2 Sam. 11). But the measure of a man of God is not in his sin but in his repentance. Psalm 51 is a beautiful testimony to how deeply David was grieved at the depth of his own sin (Psa. 51:1; 2 Sam. 11:26) (Michael Bushell, Songs of Zion, 87).
