N60: (We are charged) not to blaspheme · Sacred Scriptures Research Suite

Maimonides

(We are charged) not to blaspheme, as it is said, “Thou shalt not revile God” (Ex. 22:27); and in regard to the penalty, it is said, “And he that blasphemeth the name of the Lord shall surely be put to death” (Lev. 24:16). The general principle is that wherever the Scripture prescribes the penalty of excision or a judicial sentence of capital punishment, the offence is the violation of a prohibition. The only exceptions are Circumcision and the Passover, which are affirmative precepts, while their neglect involves the penalty of excision.
