NET

21 the men of her city must bring the young woman to the door of her father’s house and stone her to death, for she has done a disgraceful thing in Israel by behaving like a prostitute while living in her father’s house. In this way you will purge the evil from among you.

Darby

21 then they shall bring out the damsel unto the entrance of her father's house, and the men of her city shall stone her with stones that she die: because she hath wrought infamy in Israel, committing fornication in her father's house; and thou shalt put evil away from thy midst.

KJV

21 Then they shall bring out the damsel to the door of her father's house, and the men of her city shall stone her with stones that she die: because she hath wrought folly in Israel, to play the whore in her father's house: so shalt thou put evil away from among you.
