Mishneh Torah, Foundations of the Torah
To know this matter is a mandatory commandment, saying: "I am the Lord thy God" (Ex. 20,2); therefore, whosoever supposes that there is another god besides This One, (1) violates a prohibitive commandment, saying: "Thou shalt have no other gods before me" (Ibid. –3), and is an atheist, denying the great principle upon which everything depends.
Mishneh Torah, Positive Mitzvot
To know that there is a God, as it is said, “I am the Lord, thy God” (Ex. 20:2; Deut. 5:6).
Mishneh Torah, Negative Mitzvot
The first of the negative precepts is not to entertain the idea that there is any god but the Eternal, as it is said, “Thou shalt have no other gods before me” (Ex. 20:3).
