'Rich' in the Bible

If a person doesn't have a kinsman redeemer, but has become rich and found sufficient means for his redemption,

"If a resident alien or traveler becomes rich, but your relative who lives next to him is so poor that he sells himself to that resident alien or traveler among you or to a member of the resident alien's family,

His uncle or his uncle's son may redeem him or any blood relative from his tribe may redeem him. If he becomes rich, then he may redeem himself.
