'Unripe' in the Bible

"He will shake off his unripe fruit like the vine, and he will cast off his blossom like the olive tree;

"In those days they will say no longer, '{Parents} have eaten unripe fruit, and [the] teeth of [the] children {are set on edge}.'

{But} each will die because of his iniquity, {everyone} who eats the unripe fruit, their teeth will {be set on edge}.

"{What do you mean by} quoting this proverb about the land of Israel, {saying}, 'The fathers, they ate unripe fruit, and the teeth of the child became blunt.'

and the stars of heaven fell to the earth like a fig tree throws down its unripe figs [when] shaken by a great wind.
