Deuteronomy 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.

Deuteronomy 22:30 In-Context

28 If a man findeth a damsel (who is a) virgin, that hath no spouse, and taketh, and doeth lechery with her, and the thing cometh to the doom, (If a man findeth a young woman who is a virgin, who hath no spouse, and he taketh hold of her, and doeth lechery with her, and the thing cometh to be known,)

29 he that slept with her shall give to the father of the damsel fifty shekels of silver, and he shall have her to wife, for he made her low; he shall not be able to forsake her, in all the days of his life. (he who slept with her shall give the young woman's father fifty shekels of silver, and he shall have her for his wife, for he made her low; he shall not be able to divorce her, all the days of his life.)

30 A man shall not take his father's wife, neither he shall show her private(s).
