היא שהורנו בדיני נחלות. והוא אמרו יתעלה איש כי ימות ובן אין לו, ומכלל דין זה בלא ספק היות הבכור יורש פי שנים שזה משפט ממשפטי הירושות. וכבר התבארו משפטי מצוה זו בח' וט' מבתרא. (פינחס, בי"א פרקים בנחלות):

**Sefaria Edition 2021, Translated by Rabbi Francis Nataf:**
That is that He instructed us about the laws of inheritance. And that is His, may He be exalted, saying, "‘If a man dies and he has no son" (Numbers 27:8). And included in this law without a doubt is that the first born [son] inherits double, as this is one of the regulations of inheritances. And all the regulations of this commandment have already been explained in [Chapter] 8 and 9 of [Bava] Batra. (See Parashat Pinchas; Mishneh Torah, Inheritances 1-11.)
