Shenei Luchot HaBerit
לא יוכל בעלה הראשון לשוב לקחתה . On the prohibition to take back a wife one has divorced if she had remarried in the interval: There may be an allusion here to the soul which has been reincarnated in an inferior body as a penalty for having committed serious sins in a previous incarnation. Such a soul has a chance to rehabilitate itself and its previous life only as long as it is within the body to which it has been re-assigned. If it fails to exploit this second chance, לא יוכל בעלה הראשון לשוב לקחתה, her first husband, i.e. the body it inhabited originally, cannot reunite with this soul [at he time of the resurrection. Ed.]
