At sinabi ni Noemi: “Bumalik kayo, mga anak ko; bakit kayo sasama sa akin? Mayroon pa ba akong mga anak na lalaki sa aking sinapupunan na maaaring maging mga asawa ninyo?
Ibn Ezra
"Are there yet any more sons in my womb?" Many of our colleagues thought that this response was directed at those who deny (the custom), not realizing that our ancestors transmitted that levirate marriage (yibbum) applies to brothers from the father, not from the mother. She was simply saying to them, if I had sons in my womb, I would give them to you in place of the deceased. This is a manner of affection, not according to the practice of levirate marriage.
