Matthew Poole and continuators on Jeremiah 31:29

29 In those dayes they shall say no more; The fathers have eaten a sowre grape, and the childrens teeth are set on edge .

That is, we are punished for our Fathers sins, which yet God may justly do, and none questioneth the justice of man in the case, depriving children of their patrimonial Estates for their Parents Treasons, nor more then God threatneth in the second Commandment. God indeed Ezek. 18.2. seemeth displeased at their use of this Proverb, but the reason is, because they so used it, as to acquit themselves, intimating they were guiltless, and suffered only for the sins of their Parents, whereas that was false, otherwise the punishment of children for the sins of their Parents, was no more then God had threatned, Exod. 20.5. and 34.7. chap. 15.4. But faith God your captivity shall, as to you, expiate your Parents guilt past, and you shall no more say so.
