Leviticus 18:6-18

LEVITICUS—NOTE ON Leviticus 18:6 These laws prohibit sexual relations (approach... to uncover nakedness), and therefore marriage, between people who are too closely related, either by blood (mother, sister, granddaughter, aunt) or by marriage (stepmother, stepsister, stepdaughter, stepgranddaughter, sister-in-law, daughter-in-law, aunt by marriage). No mention is made of the daughter, probably because this prohibition was already well known in the laws of other cultures. The rules enforce a distinction between family affection and erotic love, which protects the well-being of the community.
