David, a man after God’s own heart, sinned against God. The Bible does not cover up the sins of its heroes and leaders; rather they are exposed.

Reading today in 2 Samuel 11 through 13.

And it came to pass, after the year was expired, at the time when kings go forth to battle, that David sent Joab, and his servants with him, and all Israel; and they destroyed the children of Ammon, and besieged Rabbah. But David tarried still at Jerusalem.  And it came to pass in an eveningtide, that David arose from off his bed, and walked upon the roof of the king’s house: and from the roof he saw a woman washing herself; and the woman was very beautiful to look upon.  And David sent and enquired after the woman. And one said, “Is not this Bathsheba, the daughter of Eliam, the wife of Uriah the Hittite?”  And David sent messengers, and took her; and she came in unto him, and he lay with her; for she was purified from her uncleanness: and she returned unto her house. And the woman conceived, and sent and told David, and said, “I am with child.” And David sent to Joab, saying, “Send me Uriah the Hittite.” And Joab sent Uriah to David.  And when Uriah was come unto him, David demanded of him how Joab did, and how the people did, and how the war prospered.  And David said to Uriah, “Go down to thy house, and wash thy feet.” And Uriah departed out of the king’s house, and there followed him a mess of meat from the king.  But Uriah slept at the door of the king’s house with all the servants of his lord, and went not down to his house.  And when they had told David, saying, “Uriah went not down unto his house,” David said unto Uriah, “Camest thou not from thy journey? Why then didst thou not go down unto thine house?…”
2 Samuel 11:1-10
