Leviticus 18:11
““‘You shall not uncover the nakedness of your father’s wife’s daughter, conceived by your father, since she is your sister.”
What does Leviticus 18:11 mean?
This law addresses sexual relationships within extended family, specifically protecting a half-sister (your father's daughter through another relationship). The phrase "uncover the nakedness" is the biblical way of referring to sexual relations. The point is simple: family bonds create a sacred boundary that shouldn't be crossed, and this applies even when you share only one parent. For people in ancient Israel, these laws helped establish clear family structures and prevented the harm that comes from blurred relational lines within a household.
