foolish people will gain understanding when the foal of a wild donkey is born a man

Since a wild donkey can never give birth to a man, this means that foolish people will never get understanding. Alternate translation: "foolish people would be able to get understanding only if a wild donkey could give birth to a man" or "it is as impossible for a foolish person to get understanding as it is for a donkey to give birth to a man" (See: rc://en/ta/man/jit/figs-irony)

But foolish people will gain understanding
