The cited verse
The Hebrew (Masoretic Text)

In Maimonides’ words
How Maimonides defines this commandment in his Sefer HaMitzvot — his own words, shown as a primary source.
הזהירנו מגלות ערות בת הבת. והוא אמרו ערות בת בתך לא תגלה ערותה וגו':
He prohibited us from sexual intercourse with the daughter of the daughter. And that is His saying, "The nakedness of [...] your daughter's daughter; you shall not uncover their nakedness, etc." (Leviticus 18:10).

How later traditions received this commandment
How later traditions read or reworked this commandment, each attributed to its own voice. The catalog’s own classification of each reception is shown as it records it, never adopted as GEBible’s.
Qumran (the Dead Sea Scrolls)
- CD 5:7-11 The catalog describes this reception as: stringent reinterpretation (extends Lev 18 kin prohibitions by analogy — explicitly to nieces; illustrative of the generalizing logic applied to lineal descendants)
Philo of Alexandria
- De Specialibus Legibus 3.20-25 rationalized it
Josephus
- Ant. 3.274-275 affirmed it
The Qur'an and hadith
- Q 4:23 carried a parallel
Beside the older legal codes of its world
The commandment set beside the ancient Near-Eastern legal collections scholars compare it to — a descriptive comparison, not a claim of dependence.
- hittite laws discrete sexual/incest offenses (individual cases, not a systematic kin catalogue) Relationship to the parallel: parallel with divergence §§189-195 Roth, Law Collections 2nd ed. (1997)
Where this commandment meets modern human-rights frameworks
One modern normative lens, attributed to it — not GEBible’s assessment. Each row names the framework it measures against and the catalog’s own classification of the relation.
This framework catalogues tensions; it records agreement in only one of its entries. The near-total tension rate is the shape of the instrument, not a finding.
No tension with the catalogued modern frameworks is recorded here.
