2 Samuel 12:14

thou hast given great occasion, &c. The enemies of Jehovah would mock and blaspheme Him, when they saw His chosen representative, the King of Israel, thus breaking His law. To divorce Bath-sheba now would be a further wrong. Yet if he was not punished men might answer yes to the question "May one be pardoned and retain the offence?" And therefore a long series of chastisements, beginning with the death of the child, must unequivocally declare the divine judgment on such sin.
