II. That they shall be reckoned with no further for the sins of their fathers (v. 29, 30): They shall say no more (they shall have no more occasion to say) that God visits the iniquity of the parents upon the children, which God had done in the captivity, for the sins of their ancestors came into the account against them, particularly those of Manasseh: this they had complained of as a hardship. Other scriptures justify God in this method of proceeding, and our Saviour tells the wicked Jews in his days that they should smart for their fathers' sins, because they persisted in them, Matt. xxiii. 35, 36. But it is here promised that this severe dispensation with them should now be brought to an end, that God would proceed no further in his controversy with them for their fathers' sins, but remember for them his covenant with their fathers and do them good according to that covenant: They shall no more complain, as they have done, that the fathers have eaten sour grapes and the children's teeth are set on edge (which speaks something of an absurdity, and is an invidious reflection upon God's proceedings), but every one shall die for his own iniquity still; though God will cease to punish them in their national capacity, yet he will still reckon with particular persons that provoke him. Note, Public salvations will give no impunity, no security, to private sinners: still every man that eats the sour grapes shall have his teeth set on edge. Note, Those that eat forbidden fruit, how tempting soever it looks, will find it a sour grape, and it will set their teeth on edge; sooner or later they will feel from it and reflect upon it with bitterness. There is as direct a tendency in sin to make a man uneasy as there is in sour grapes to set the teeth on edge.
