'Prospers' in the Bible

But if a man {does not have} a redeemer, then {he prospers} and he finds enough for his redemption,

or his uncle or his uncle's son may redeem him, or {one of} {his close relatives} from his clan may redeem him; or [if] {he prospers}, he may redeem himself.

And so, he is like a tree planted by streams of water that gives its fruit in its season; its leaf also does not wither. Therefore all that he does prospers.
