Leviticus 18:10

8 You must not have sexual relations with your father’s wife; it would dishonor your father.

9 You must not have sexual relations with your sister, either your father’s daughter or your mother’s daughter, whether she was born in the same home or elsewhere.

You must not have sexual relations with your son’s daughter or your daughter’s daughter, for that would shame your family.

11 You must not have sexual relations with the daughter of your father’s wife, born to your father; she is your sister.

12 You must not have sexual relations with your father’s sister; she is your father’s close relative.

This was said to Israel at a particular time, so it is wise to read it together with the surrounding text. Do read the surrounding verses too, because the context often says more than a single verse.
