Leviticus 20:19

20:19 You must not expose the nakedness of your mother’s sister and your father’s sister, for such a person has laid bare his own close relative. They must bear their punishment for iniquity.

Leviticus 22:25

22:25 Even from a foreigner you must not present the food of your God from such animals as these, for they are ruined and flawed; they will not be acceptable for your benefit.’”
