Leviticus 20:17: And if a man shall take his sister, his father's daughter, or his mother's daughter, and see her nakedness, and she see his nakedness; it [is] a wicked thing; and they shall be cut off in the sight of their people: he hath uncovered his sister's nakedness; he shall bear his iniquity.
Contradiction with Deuteronomy 27:22
This verse contradicts Genesis 20:12 by declaring a curse on anyone who lies with his sister, the daughter of his father or mother.

Contradiction with 1 Corinthians 5:1

Contradiction with Ezekiel 22:11

Ezekiel 22:11: And one hath committed abomination with his neighbour's wife; and another hath lewdly defiled his daughter in law; and another in thee hath humbled his sister, his father's daughter. [one: or, every one] [another: or, every one] [lewdly: or, by lewdness]
Paradox #1
The verse suggests a family relationship between Abraham and Sarah that might seem inconsistent with later biblical laws that discourage marriage between close relatives. However, cultural and historical contexts differ across different parts of the Bible, so what may appear as a contradiction might have been acceptable in earlier times.
Paradox #2
Genesis 20:12 mentions that Sarah is Abraham's half-sister, which creates a contradiction with earlier passages where both Abraham and Sarah's full lineage is detailed, suggesting they have different parents. This inconsistency creates confusion about the family relationship described in earlier chapters.
Paradox #3
The contradiction in this verse could be seen in the practice of marrying a close relative, which is generally considered unacceptable in many cultures and later biblical laws. This creates a conflict between cultural norms and biblical narratives.
Paradox #4
Genesis 20:12 could present a numerical inconsistency or contradiction when considering family lineage. It mentions Sarah as both Abraham's wife and half-sister, which might seem to conflict with other genealogical details or cultural expectations regarding marriage within the family.
