Halakhah su Deuteronomio 21:21

He prohibited us from being gluttonous and drunk with food and drink in the days of youth and under the conditions of the law of the stubborn and rebellious [son]. And that is His saying, "'You shall not eat with the blood" (Leviticus 19:26). And the explanation of this is that a stubborn and rebellious son is included in [those things] that are liable for a death penalty of the court; and the language of the Torah about it (Deuteronomy 21:21) is that it is [punished] with stoning. And it has already been explained at the introduction of this essay (Sefer HaMitzvot Shoreshim 14) that anything for which one is liable for excision or a death penalty of the court is a negative commandment, except for the Pesach-sacrifice and circumcision - as we explained. If so, since the gluttonous and drunk son under the specified conditions is sentenced to stoning, we know that the act is perforce prohibited to him - since the punishment was explicit. Hence we must search for the prohibition, since Scripture did not punish [for something] unless it prohibited [it]. And the language of the Gemara, Sanhedrin (Sanhedrin 63a), is, "From where [do we know] the prohibition of a stubborn and rebellious son? [Hence] we learn to say, 'You shall not eat with the blood'" - meaning to say, do not eat an eating that brings about the spilling of blood; and that is the eating of a stubborn and rebellious son, as he is liable for death because of it. And when he eats this bad eating in those not good ways, he has already transgressed the negative commandment - even though this is a general negative commandment, as we explained in the ninth principle (Sefer HaMitzvot, Shorashim 9). For this is not difficult: Since the punishment is explicit, we do not concern ourselves with whether the prohibition is bona fide or whether it is from a general negative commandment. And the regulations of this commandment have already been explained in Chapter 8 of Sanhedrin. (See Parashat Kedoshim; Mishneh Torah, Rebels 7.)
