以掃就往以實瑪利那裡去，在他原有的妻子之外，又娶了瑪哈拉為妻；瑪哈拉是亞伯拉罕的兒子以實瑪利的女兒，尼拜約的妹妹。
Mishnah Yevamot
A man is permitted to marry [the relative] of a woman [whom he has] raped or seduced. He who rapes or seduces [a relative] of his married wife, is guilty. A man may marry a woman whom his father has raped or seduced or a woman whom his son has raped or seduced. Rabbi Yehudah forbids [marriage] with a woman whom one’s father has raped or seduced.
