'Prospers' in the Bible

If a man has no family redeemer, but he prospers and obtains enough to redeem his land,

“If a foreigner or temporary resident living among you prospers, but your brother living near him becomes destitute and sells himself to the foreigner living among you, or to a member of the foreigner’s clan,

His uncle or cousin may redeem him, or any of his close relatives from his clan may redeem him. If he prospers, he may redeem himself.
