וָאֶעֱבֹ֨ר עָלַ֜יִךְ וָאֶרְאֵ֗ךְ וְהִנֵּ֤ה עִתֵּךְ֙ עֵ֣ת דֹּדִ֔ים וָאֶפְרֹ֤שׂ כְּנָפִי֙ עָלַ֔יִךְ וָאֲכַסֶּ֖ה עֶרְוָתֵ֑ךְ וָאֶשָּׁ֣בַֽע לָ֠ךְ וָאָב֨וֹא בִבְרִ֜ית אֹתָ֗ךְ נְאֻ֛ם אֲדֹנָ֥י יְהוִ֖ה וַתִּ֥הְיִי לִֽי׃
Now when I passed by thee, and looked upon thee, and, behold, thy time was the time of love, I spread my skirt over thee, and covered thy nakedness; yea, I swore unto thee, and entered into a covenant with thee, saith the Lord GOD, and thou becamest Mine.
Ruth
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.)]
Deuteronomy
A man may not marry his father’s wife, and may not expose the edge of his father’s garment.
