וּמַכֵּ֥ה אָבִ֛יו וְאִמּ֖וֹ מ֥וֹת יוּמָֽת׃
און דער װאָס שלאָגט זײַן פֿאָטער, אָדער זײַן מוטער, זאָל טײטן געטײט װערן.
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.
