Jewish views on incest deal with the sexual relationships which are prohibited by Judaism and rabbinic authorities on account of a close family relationship that exists between persons. Such prohibited relationships are commonly referred to as incest or incestuous, though that term does not appear in the biblical and rabbinic sources. The term mostly used by rabbinic sources is "forbidden relationships in Judaism." Relationships forbidden in the Hebrew Bible The Hebrew Bible sets out several lists of relationships sexual relations between which are forbidden. Two lists appear in the Book of Leviticus and one list appears in the Book of Deuteronomy. The lists only mention relationships with female relatives; excluding lesbianism, this implies that the list is addressed to men. In the Hebrew Bible, sexual relationships between siblings are forbidden to Jews but permissible to Gentiles (non-Jews). Since the lists would then describe women with whom it is forbidden for a man to have a relationship, they also indirectly imply a list of men with whom it is forbidden for a woman to have a relationship. The lists are as follows: One of the most notable features of each list is that sexual relations between a man and his own daughter are not explicitly forbidden, although the first relation mentioned after the Levitical prohibition of sex with "near kin" is that of "thy father." (This assumes that the Torah is only speaking to men. If it is speaking to everyone, then a woman is not allowed to have sex with her father. It also explicitly prohibits having sex with a woman and her daughter. A man's daughter is obviously also the daughter of a woman with whom he had sexual relations.) The Talmud argues that this absence is because the prohibition was obvious, especially given the proscription against a relationship with a granddaughter. As with the case of a man's own daughter, the shortness of the list in Leviticus 20, and especially of that in Deuteronomy, are explained by classical Jewish scholarship as being due to the obviousness of the missing prohibitions. Apart from the case of a man marrying his daughter, the list in Leviticus 18 roughly produces the same rules as were followed in early (pre-Islamic) Arabic culture. However, most tribal nations also disliked exogamous marriage – marriage to completely unrelated people. Judaism's view is that prior to the giving of the Torah at Mount Sinai, some of
