God layeth up his iniquity for his children: he rewardeth him, and he shall know it.

Ye say , God layeth up his iniquity for his children. Let him recompense it unto himself, that he may know it:

God shall lay up the sorrow of the father for his children: and when he shall repay, then shall he know.

God layeth up for his sons his sorrow, He giveth recompense unto him, and he knoweth.

God lays up his iniquity for his children: he rewards him, and he shall know it.

You say, God keeps punishment stored up for his children. Let him send it on the man himself, so that he may have the punishment of it!

God will preserve the grief of the father for his sons, and, when he repays, then he will understand.

God layeth up his iniquity for his children - Margin, that is, "the punishment of iniquity." This is a reference evidently to the opinion which "they" had maintained. It may be rendered, "You say that God layeth up iniquity," etc. They had affirmed that not only did God, as a great law, punish the wicked in this life, but that the consequences of their sins passed over to their posterity; or, if "they" were not punished, yet the calamity would certainly come on their descendants; see Job 18:19-20; Job 20:10, Job 20:28. This is the objection which Job now adverts to. The statement of the objection, it seems to me, continues to Job 21:22, where Job says, that no one can teach God knowledge, or prescribe to him what he should do, and then goes on to say, that the "fact" was far different from what they maintained; that there was no such exact distribution of punishments; but that one died in full strength, and another in the bitterness of his soul, and both laid down in the dust, together. This view seems to me to give better sense than any other interpretation which I have seen proposed.
He rewardeth him, and he shall know it - That is, you maintain that God will certainly reward him in this life, and that his dealings with him shall so exactly express the divine view of his conduct, that he shall certainly know what God thinks of his character. This opinion they had maintained throughout the argument, and this Job as constantly called in question.

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.

God layeth up his iniquity for his children,.... This is a prevention of an objection which Job foresaw his friends would make, and therefore takes it up and answers to it; you will say, that, be it so, that the wicked are for the most part prosperous, and their prosperity continues; God does not punish them now for their sins in their own persons, yet he will punish them in their children, for whom he reserves the punishment of their iniquity: this way go many of the Jewish commentators (y), in which they are followed by many Christian interpreters (z); and, as it seems, very rightly; now this Job grants, that so it is, God takes notice of the iniquities of men, and lays them up in his mind, and puts them down in the book of his remembrance; he reserves the punishment of their iniquities for their children, iniquity being often put for the punishment of it; this is laid up among his stores of vengeance, and is treasured up against the day of wrath; and when they have filled up the measure of their father's sins by their own transgressions, the deserved punishment shall be inflicted, according to Exodus 20:5; but this will not clear the case, nor support the notions and sentiments of Job's friends, who had all along given out, that wicked men are punished themselves as well as their children; and that, if they are at any time in prosperous circumstances, it is only for a little while; and therefore agreeably to such notions God should take other methods with them, not punish their children only, but themselves, as Job argues in answer to the objection in Job 21:18,
he rewarded him, and he shall know it; or "he should reward him, and he should know it" (a); and so the word "should" is to be put instead of "shall" in Job 21:20, which directs to the true sense of these clauses: and the meaning of Job is, that according to the sentiments of his friends, God should reward a wicked man while he lives in his own body, and not in his posterity only; he should render to them a just recompence of reward of their evil works, the demerit of their sins; and in such a manner, that they should know it, be sensible of it, and feel it themselves, and perceive the evil of sin in the punishment of it; see Hosea 9:7.

Equally questionable is the friends' assertion that if the godless himself is not punished, the children are (Job 18:19; Job 20:10); and that God rewardeth him here for his iniquity, and that he shall know it to his cost. So "know" (Hosea 9:7).

Layeth up - In his treasures, Romans 2:5. Iniquity - The punishment of his iniquity; he will punish him both in his person and in his posterity.
