Midrash su Rut 1:9

“May the Lord grant you that you find rest, each woman in the house of her husband. She kissed them; and they raised their voices, and wept” (Ruth 1:9).
“May the Lord grant [yitten] you” – Rabbi Yosei said: All the goodness and consolations that the Holy One blessed be He was destined to grant to Solomon, as it is written: “God granted [vayitten] wisdom to Solomon” (I Kings 5:9), will be from you.¹¹⁰This is an allusion to the fact that David and Solomon will descend from Ruth. “And find rest [umtzena]” – umtzena is written,¹¹¹The word is written without the concluding heh. one will find [rest], two will not find. “Each woman in the house of her husband” – from here [it may be derived] that there is satisfaction for a woman only in her husband’s house.
“Naomi said: Return my daughters; why would you go with me? Do I have more sons in my womb that would be husbands for you?” (Ruth 1:11).
“They raised their voices, and wept, and they said to her…Naomi said: Return my daughters, why would you go with me? Do I have more sons in my womb that would be husbands for you?” (Ruth 1:9–11). Does a person perform levirate marriage with the wife of his brother with whom he did not coexist?¹¹²If a married man dies without children, his brother marries his widow in a procedure called levirate marriage (see Deuteronomy 25:5–6). However, this may not be done if the brother had not yet been born during the deceased brother’s lifetime (see Yevamot 17b).
