'Uncle's' in the Bible

As for a man who lies with his aunt, he has exposed his uncle's nakedness--they shall bear their sin; they shall die childless.

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.

He was raising Hadassah, that [is] Esther, his uncle's daughter, for she did not have a father or a mother; the young woman [had] a beautiful figure and [was] very attractive. When her father and mother died, Mordecai had taken her as his daughter.
