Original sentence: In the critical-historical view, the betrothal was effected simply by "purchasing" the girl from her father (or guardian).Rashi understands Rachel and Leah's complaint to Jacob ("we are considered strangers to him for he has sold us") as saying that is was not normal for a father to sell his daughters, at least not without also giving them a dowry.Rashi understands mohar as a form of Ketubah, an agreement to pay a certain amount upon divorce, and Nachmanides understands it as sovlanut, a sort of dowry or engagement present.The traditional commentators do not necessarily explain mohar this way
