21 then they shall bring out the young lady to the door of her father's house, and the men of her city shall stone her to death with stones, because she has done folly in Israel, to play the prostitute in her father's house: so you shall put away the evil from the midst of you.

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, 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.
