You must not have sexual relations with the sister of your mother or your father, for it is exposing one’s own kin; both shall bear their iniquity.
None of you are to approach any close relative to have sexual relations. I am the LORD.
And Amram married his father’s sister Jochebed, and she bore him Aaron and Moses. Amram lived 137 years.
You must not have sexual relations with your father’s sister; she is your father’s close relative.
