God layeth up his iniquity for his children: he rewardeth him, and he shall know it. God layeth up his iniquity for his children - This is according to the declaration of God, Exodus 20:5 : "Visiting the iniquity of the fathers upon the children, unto the third and fourth generation of them that hate me." This always supposes that the children, who are thus visited, have copied their parents' example; or that ill-gotten property is found in their hands, which has descended to them from their wicked fathers; and of this God, in his judgments, strips them. It is, however, very natural to suppose that children brought up without the fear of God will walk in the sight of their own eyes, and according to the imaginations of their own hearts.
He rewardeth him, and he shall know it - He shall so visit his transgressions upon him, that he shall at last discern that it is God who hath done it. And thus they will find that there would have been profit in serving him, and safety in praying unto him. But this they have neglected, and now it is too late.
