Deutéronome 22:30 Meaning and Commentary

Deuteronomy 22:30

A man shall not take his father's wife
Not marry her, whether his own mother, or a stepmother; or even, as Aben Ezra thinks, anyone that was deflowered by his father. Jarchi interprets it of his father's brother's wife, which he was obliged to marry by virtue of the law in ( Deuteronomy 25:5 )

nor discover his father's skirt;
or lie with her his father had thrown his skirt over, or married; and which being the first, is mentioned here as a sample to all the rest forbidden ( Leviticus 18:7 ) or, as Bishop Patrick expresses it, is a "short memorandum", to make them careful to observe all the other laws respecting incestuous marriages and copulations there delivered.

Deutéronome 22:30 In-Context

28 Si un homme trouve une jeune fille vierge, qui ne soit point fiancée, et que, la saisissant, il couche avec elle, et qu'ils soient trouvés;

29 L'homme qui a couché avec elle donnera au père de la jeune fille cinquante pièces d'argent, et elle sera sa femme, parce qu'il l'a humiliée. Il ne pourra pas la renvoyer tant qu'il vivra.

30 Nul ne prendra la femme de son père, ni ne lèvera le bord de la couverture de son père.
