Komentarz do Liczb 15:23

את כל אשר צוה וגו׳ EVEN ALL THAT [THE LORD] HATH COMMANDED [YOU] etc. — This tells us that he who acknowledges the divinity of an idol is like one who denies the Torah in its entirety and all that the prophets prophesied, because it states, “[and if yo have erred and not done … all that the Lord hath commanded by Moses] from the day that the Lord commanded (Moses), and hence forth [throughout all your generations]” (cf. Sifrei Bamidbar 111:1).

את כל אשר צוה ה' אליכם ביד משה. All the sins referred to were committed inadvertently. The Torah simply means that the transgression of the single commandment not to commit idolatry is equivalent of the sinner having transgressed all the commandments G’d had commanded.

מן היום אשר צוה ה' והלאה, All the commandments in the Torah were commanded after the first 2 of the 10 Commandments.
