A common misinterpretation of Leviticus 18:11 is viewing it as merely an archaic cultural taboo limited to ancient Israel, thereby dismissing its enduring moral principle against incestuous relations with close blood relatives like half-siblings, which undermines the passage's role in God's universal call to sexual holiness; others erroneously distinguish it to permit relations with step-siblings lacking full blood ties, ignoring the explicit reference to a daughter 'begotten of thy father,' or twist it out of context to fuel debates on unrelated issues like homosexuality, diluting its clear intent to forbid familial sexual immorality.
Leviticus 18:11
King James Version (1769)
11 The nakedness of thy father’s wife’s daughter, begotten of thy father, she is thy sister, thou shalt not uncover her nakedness.
Leviticus 18:11 prohibits sexual relations with one's half-sister, specifically the daughter born to one's father by another wife, as part of a broader divine law code aimed at preserving Israel's holiness and distinguishing them from the immoral practices of surrounding nations like Egypt and Canaan; this command upholds the sanctity of family structures, prevents exploitation within households, and reflects God's design for purity, relational integrity, and moral order in human sexuality.
