'Prospers' in the Bible

If a man has no redeemer, but he prospers and gains enough for its redemption,

"'If a resident foreigner who is with you prospers and your brother becomes impoverished with regard to him so that he sells himself to a resident foreigner who is with you or to a member of a foreigner's family,

or his uncle or his cousin may redeem him, or anyone of the rest of his blood relatives -- his family -- may redeem him, or if he prospers he may redeem himself.
