'Uncle's' in the Bible

"If a man has sexual relations with his uncle's wife, he has exposed his uncle's nakedness. They are to bear responsibility for punishment of their sin. They'll die childless.

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.

for Mahlah, Tirzah, Hoglah, Milcah, and Noah: Zelophehad's daughters married their uncle's sons.
