Танах к Дварим 23:1

And he said: Who are you? And she said: I am Ruth, your maidservant. Spread your [garment-] corner over your maidservant [i.e., take me as your wife], for you are a redeemer [(to redeem our inheritance, that Na'ami and I must sell. Acquire it, and me along with it, so that the dead one's name will be perpetuated thereby. When I come to the field (of the inheritance), people will say: This was the wife of Machlon.)]

Et je passai près de toi et vis que tu étais arrivée à l’âge des amours; j’étendis mon vêtement sur toi et couvris ta nudité; je m’engageai à toi par serment et fis alliance avec toi, dit le Seigneur Dieu, et tu fus à moi.

The nakedness of your father and the nakedness of your mother you shall not uncover; she is your mother, you shall not uncover her nakedness.
