וְאִם־אֵ֥ין ל֖וֹ בַּ֑ת וּנְתַתֶּ֥ם אֶת־נַחֲלָת֖וֹ לְאֶחָיו׃
At kung wala siyang anak na babae, ibibigay ninyo ang kanyang mana sa kanyang mga kapatid na lalaki.
Mishnah Yevamot
If one has any kind of brother, [that brother] requires his brother’s wife to have yibbum, and he is his brother in every respect, except for a brother born from a female slave or a non-Jewish woman. If one has any kind of son, [that son] exempts his father’s wife from yibbum, and he is liable for striking or cursing [his father], and he is his son in every respect, except for the son of a female slave or a non-Jewish woman.
