In those days they shall say no more,.... The following proverb or byword; they should have no occasion to use it, nor should they choose to use it; since they would understand themselves, and the dispensations of Providence towards them, better than to use it:the fathers have eaten a sour grape, and the children's teeth are set on edge; that is, the fathers have sinned, and the children are punished for their sins.
So the Targum,"the fathers have sinned, and the children are smitten.''This was in some sense true; they were punished for their fathers' sins in the captivity, particularly for Manasseh's; nor was it unusual with God to visit the iniquities of the fathers upon the children; nor at all unjust, since they were a part of their parents, and especially since they were guilty of the same sins; nor is it thought unjust among men to punish children for the treason of their parents, as every sin is treason against God.
