2 Samuel 12:13-16

David said to Nathan, “I have sinned against the LORD.” And Nathan said to David, “The LORD also has put away your sin; you shall not die. Nevertheless, because by this deed you have utterly scorned the LORD, the child who is born to you shall die.” Then Nathan went to his house. And the LORD afflicted the child that Uriah’s wife bore to David, and he became sick. David therefore sought God on behalf of the child. And David fasted and went in and lay all night on the ground.
