Incest in the Bible refers to sexual relations between certain close kinship relationships which are prohibited by the Hebrew Bible. These prohibitions are found predominantly in {{bibleverse||Leviticus|18:8-18|NIV}} and {{bibleverse-nb||Leviticus|20:11-21|NIV}}, but also in Deuteronomy. The biblical categories of prohibited relationships does not entirely match the modern definitions of prohibited incestuous relations in force in various countries or of the various Christian denominations. (see Affinity (canon law) and Laws regarding incest.)

A few books of the Bible, particularly the early parts of the Torah, contain narratives in which certain individuals, from the same family as one another, engage in sexual intercourse together; while this could be construed as incest, endogamy is an alternative interpretation. The Bible does not, for example, forbid cousins from marrying, but it does prohibit sexual relations with several other close relatives.

Definition

In ancient times, tribal nations preferred endogamous marriage{{snd}} marriage to one's relatives;^[1] the ideal marriage was usually that to a cousin, and it was often forbidden for an eldest daughter to even marry outside the family.^[1] Marriage to a half-sister, for example, is considered incest by most nations today, but was common behaviour for Egyptian pharaohs; similarly, the Book of Genesis portrays Sarah as marrying Abraham, her half-brother, without criticising the close genetic relationship between them,^[2] and the Book of Samuel treats the marriage of a royal prince to his half-sister as unusual, rather than wicked.^[1]

Leviticus 18 and 20 lists the prohibited incestuous relationships,^[3] and two chapters later specifies punishments for specific incestuous unions, but this second list of unions is much shorter than the first;^[4] critical scholars regard the lists as having originally been independent documents, bound together at a later point.^[5][6][7] The Deuteronomic Code gives a yet more simple list of forbidden relationships{{snd}} a man's parent's daughter (including his sister), a man's father's wife (including his mother), and a man's mother-in-law.^[8][9] These lists of forbidden unions compare as follows (the relations highlighted in red are those that are forbidden):

One of the most notable features of all the lists is that sexual activity between a man and his own daughter is not explicitly forbidden. Although the first relation mentioned after the Levitical prohibition of sex with "near kin" names that of "thy father",^[10] it must be taken into account that the Hebrew original text only addresses male Jews with regard to their female relatives.^[11] The talmud argues that the absence is because the prohibition was obvious, especially given the proscription against a relationship with a granddaughter,^[12] although some biblical scholars have instead proposed that it was originally in the list, but was then accidentally left out from the copy on which modern versions of the text ultimately depend, due to a mistake by the scribe.^[13] The second list in the Holiness code noticeably differs from the first by not including the closer relatives, and it might be assumed that obviousness is the explanation here as well.^[1] One might argue that the explicit prohibition against engaging in sexual activity with a woman as well as with her daughter,^[14] implicitly forbids sexual activity between a man and his daughter. However, the rationale might suggest otherwise (the original text is unclear here), since it mentions only that "they" (i.e., the woman and the daughter) are related.^[15] John Calvin did not consider the father-daughter-relation to be explicitly forbidden by the bible, but regarded it as immoral nevertheless.^[16]

Apart from the case of the daughter, the first incest list in the Holiness code roughly produces the same rules as were followed in early (pre-Islamic) Arabic culture;^[1] in Islam, these pre-existing rules were made statutory.^[13] The rules in this list are, however, ignored in several prominent cases in the Torah{{snd}} Jacob is described as having married his first wife's sister,^[17][18][19] and Abraham as having a father in common with Sarah^[2] (rather than a mother, which would have been permitted by the list).

Gender-specific rules

The biblical lists are not symmetrical{{snd}} the implied rules for women are not the same - they compare as follows (blue = forbidden for men only, red = forbidden for women only, purple = forbidden for both men and women):

Specific incestuous relationships in the Bible

The Bible mentions a number of sexual relationships, most of which relate to pre-Sinai period prior to the handing down of the Mosaic law:

• In {{bibleverse||Genesis|9:20-27|9}}, Ham saw his father Noah's nakedness. The Talmud suggests that Ham may have sodomized Noah (Babylonian Talmud Sanhedrin 70a). In more recent times, some scholars have suggested that Ham may have had intercourse with his father's wife.^[22]
• Abraham's brother Nahor married his niece Milcah, the daughter of his other brother Haran.^[23]
• In {{Bibleref2|Genesis|19:30-38|9}}, living in an isolated area after the destruction of Sodom and Gomorrah, Lot's two daughters conspired to inebriate and seduce their father due to the lack of available partners. Because of intoxication, Lot "perceived not" when his firstborn, and the following night his younger daughter, lay with him. ({{Bibleref2|Genesis|19:32-35|9}}) The two children born were directly Lot's sons and indirectly his grandsons, being his daughters' sons. Likewise, their sons were also half-brothers (between them and with their mothers), having the same father, as well as cousins, having mothers that were sisters.
• In one of the tales of a wife confused for a sister, Abraham admitted that his wife Sarah is also his half-sister, on his father's side.^[2] However, in the rabbinic literature, Sarah is considered Abraham's niece (the daughter of his brother, Haran).{{Citation needed|date=February 2012}}
• Abraham's son Isaac married Rebekah, his first cousin once removed, the granddaughter of his father's brother Nahor and niece Milcah.^[24] Isaac and Rebekah's firstborn son Esau married his cousin Mahalah, daughter of his father's brother Ishmael,^[25] while their second son Jacob married his cousins Leah and Rachel, daughters of his mother's brother Laban.^[26] Marriage of cousins was not forbidden in biblical law.
• In {{bibleverse||Genesis|35:22|9}}, Jacob's firstborn son Reuben committed incest by sleeping with his father's concubine Bilhah.
• In Genesis 38, Judah, the fourth son of Jacob, mistook his daughter-in-law Tamar for a prostitute while she was veiled, and had sex with her.^[27]
• The biblical character Amram married his paternal aunt, Jochebed, the mother of Miriam, Aaron and Moses.^[28]
• In the book of 2nd Samuel, Amnon, King David's eldest son and heir to the throne, raped his half-sister Tamar; Tamar's brother, Absalom, learned of the incident and, two years later, ordered his servants to have Amnon killed.^[29] It is noteworthy that when pleading in vain with Amnon, Tamar said, "Now therefore, I pray thee, speak unto the king; for he will not withhold me from thee".^[30]
• In {{bibleverse|2 Samuel|16:22|9}}, Absalom (son of King David) is in the middle of a rebellion against his father and sleeps with his father's concubines on the roof inside a tent.
• Rehoboam son of Solomon and Naamah,^[31] married Maacah daughter of Absalom.^[32] 2 samuel 14:27 does not list Maacah as daughter of Absalom^[33] but Absalom seems having sex with wives of David, his father at the advice of Ahithophel.^[34]
• Zelophehad's daughters, Mahlah, Tirzah, Hoglah, Milcah and Noah, married their cousins on their father's side to obey Lord's command. Lord said: "no inheritance shall be transferred from one tribe to another".^[35][36]
• Caleb said, “Whoever strikes Kiriath-sepher and captures it, to him will I give Achsah my daughter as wife.” Othniel was given his cousin, Achsah, as wife.^[37][38]
