Tanakh sur Le Deutéronome 25:5

כִּֽי־יֵשְׁב֨וּ אַחִ֜ים יַחְדָּ֗ו וּמֵ֨ת אַחַ֤ד מֵהֶם֙ וּבֵ֣ן אֵֽין־ל֔וֹ לֹֽא־תִהְיֶ֧ה אֵֽשֶׁת־הַמֵּ֛ת הַח֖וּצָה לְאִ֣ישׁ זָ֑ר יְבָמָהּ֙ יָבֹ֣א עָלֶ֔יהָ וּלְקָחָ֥הּ ל֛וֹ לְאִשָּׁ֖ה וְיִבְּמָֽהּ׃

Si des frères demeurent ensemble et que l’un d’eux vienne à mourir sans postérité, la veuve ne pourra se marier au dehors à un étranger; c’est son beau-frère qui doit s’unir à elle. Il la prendra donc pour femme, exerçant le lévirat à son égard.

Ruth

And Na'ami said to her daughter-in-law: He is blessed of the L-rd for not having withheld his lovingkindness from the living [(by feeding them)] and (from) the dead [(by providing them with shrouds, etc.)]. And Na'ami said to her: The man is kin to us. He is one of our redeemers.

Ruth

On the day you buy the field from Na'ami, you (must) buy it from Ruth the Moavitess, the wife of the deceased, to establish the name of the deceased upon his inheritance [(and she will not sell it to you unless you marry her)].

Ruth

And the redeemer said: I cannot redeem it unto me lest I destroy [i.e., blemish] my seed [(Ploni Almoni mistakenly assuming that "An Ammonite and a Moavite shall not come into the congregation of the L-rd" [Deuteronomy 23:4] applies to a Moavitess as well)]. You redeem my inheritance, for I cannot redeem it.
