Deuteronomy 22:21 Meaning and Commentary

Deuteronomy 22:21

Then they shall bring out the damsel to the door of her
father's house
For his greater disgrace, and as a sort of punishment for his neglect of her education, not taking care to instruct her, and bring her up in a better manner:

and the men of her city shall stone her with stones, that she die;
which was the death this sort of adulteresses were put to; others was by strangling, and the daughter of a priest was to be burnt; see ( Leviticus 20:10 ) ( 21:9 ) , which shows that this sin was committed by her after her espousals, as Jarchi and Aben Ezra note; or otherwise it would have been only simple fornication, which was not punishable with death:

because she hath wrought folly in Israel:
a sin, as all sin is folly, and especially any notorious one, as this was; and which is aggravated by its being done in Israel, among a people professing the true religion, and whom God had chosen and separated from all others to be a holy people to himself:

to play the whore in her father's house;
where she continued after her espousals, until she was taken to the house of her husband, to consummate the: marriage; and between the one and the other was this sin committed, and which is another reason for her execution at the door of her father's house:

so shalt thou put evil away from among you;
deter others from it by such an example, and remove the guilt of it from them, which otherwise would lie upon them, if punishment was not inflicted; the Targum of Jonathan interprets it of the putting away of her that did the evil.

Deuteronomy 22:21 In-Context

19 They must make him pay about two and one-half pounds of silver to the girl's father, because the man has given an Israelite virgin a bad name. The girl will continue to be the man's wife, and he may not divorce her as long as he lives.
20 But if the things the husband said about his wife are true, and there is no proof that she was a virgin,
21 the girl must be brought to the door of her father's house. Then the men of the town must put her to death by throwing stones at her. She has done a disgraceful thing in Israel by having sexual relations before she was married. You must get rid of the evil among you.
22 If a man is found having sexual relations with another man's wife, both the woman and the man who had sexual relations with her must die. Get rid of this evil from Israel.
23 If a man meets a virgin in a city and has sexual relations with her, but she is engaged to another man,
