Tractate Sanhedrin, Herbert Danby tr. , at sacred-texts.com
9. He who has criminal connexion with a betrothed damsel 4 is guilty only if she be a virgin, betrothed, and in her father's house. If two have criminal connexion with her, the first is to be stoned and the second strangled.
10. If, however, she have received her husband in her father's house, then, although she be still a virgin, one who has criminal connexion with her is to be strangled. 1
A betrothed damsel who has committed adultery is to be stoned at the door of her father's house. If there is no door to her father's house, she is to be stoned where she committed adultery. And if it be in a heathen city, she is to be stoned at the door of the court.
102:4 Deut. 22. 23-34. The description na‘ara, ''damsel," is, according to Mishnah Niddin V. 67, only applicable to one between the age of twelve years and a day and twelve years and six months.
102:5 No longer a "damsel," but bogereth, "entering maturity," past the age of twelve years and six months.
103:1 It comes within the scope of adultery; Mishnah XI. 6b.
