Halakhah su Levitico 24:15

That He prohibited us from cursing the great God, may He be greatly exalted from that which the secterians say. And this is the matter that has been called, 'blessing' God, may He be exalted. The punishment for one who transgresses this negative commandment is indeed explicit in the Torah - that he is stoned. And that is His, may He be exalted, saying, "And he who blasphemes the name of the Lord shall surely be put to death and all the congregation shall certainly stone him" (Leviticus 24:15). However [regarding] the prohibition - behold that no verse came that is specific to this content by itself. Rather it came with a prohibition that includes this content and that besides it. And that is His saying, "Do not curse powers (elohim)" (Exodus 22:27). And in the explanation (Sanhedrin 56a), they said, "For the ineffable name, with death; and for appellations, with a prohibition." And in the Mekhilta (Mekhilta DeRabbi Shimon Bar Yochai 22:27), [it says,] "'Do not curse powers' - is to give a [prohibition] for 'blessing' God." And the regulations of this commandment have been explained in the sixth [chapter of] Sanhedrin. And you should know that this type of prohibition that includes two or three things need not be from the general negative commandments. For Scripture explained the punishment of each matter [separately] - so we know perforce that each matter was forbidden, such that [each] is a negative commandment. And since it is a principle in the Torah that it only punishes [for something] if it has prohibited [it], we will necessarily search for the prohibition. And sometimes it will be derived from an analogy and sometimes it will be included in something else, as we explained in Principle 14. It will however not be a general negative commandment unless no aspect of that which is prohibited by it is found in any place - and that is as we explained in Principle 9. However when we have prior knowledge that we are prohibited from that thing - such as His saying, "One who does this will have that done to them" - we will not be particular about the prohibition being explicit, or in one of these two ways; [or] it being specific or general. And know this. (See Parashat Mishpatim; Mishneh Torah, Mishneh Torah, Foreign Worship and Customs of the Nations 1.)
