If a man be niggardly either in a financial or a spiritual regard,
giving nothing of his money to the poor or not imparting of his
knowledge to the ignorant, he shall be punished by transmigration into a
woman.... Know thou that Sarah, Hannah, the Shunammite (2 Kings iv. 8),
and the widow of Zarepta were each in turn possessed by the soul of
Eve.... The soul of Rahab transmigrated into Heber the Kenite, and
afterward into Hannah; and this is the mystery of her words, "I am a
woman of a sorrowful spirit" (1 Sam. i. 15), for there still lingered in
her soul a sorrowful sense of inherited defilement.... Eli possessed the
soul of Jael, the wife of Heber the Kenite.... Sometimes the souls of
pious Jews pass by metempsychosis into Gentiles, in order that they may
plead on behalf of Israel and treat them kindly. For this reason have
our Rabbis of blessed memory said, "The pious of the nations of the
world have a portion in the world to come."
