2 Samuel 11:27

And when the mourning was past, David, still with the same passionate desire for the woman as before, sent and fetched her to his house, and she became his wife, and bare him a son, the child begotten in adultery. The two guilty ones wanted it to appear that the interval between their marriage and the birth of Bathsheba's child was long enough to make its birth in wedlock seem possible, an evil plan still resorted to by fornicators or adulterers to hide their sin. But the thing that David had done displeased the Lord. He took note of the transgression and prepared to punish it in due time. Sins of adultery and murder are of a nature to take faith out of the hearts of the believers and to make them children of wrath and damnation.
