Leviticus 18:22 (NOTE: The literal translation of the original Hebrew, however, is “And with male you shall not lie lyings with woman.” The word translated as “lyings” is "Miskeve" and is found elsewhere only in Genesis 49:4, where it refers to incest. In Leviticus, this verse comes in a list of prohibitions against having sex with family members, so it is reasonable to conclude that it is a prohibition against incest.)
