Not to bow down to an idol

That He prohibited us from bowing to an idol. And that is His, may He be blessed, saying, "You shall not bow to them" (Exodus 20:5). And it is clear that by our saying, idol, we mean anything worshipped besides God. And the intention is not only bowing, and nothing else. Indeed, He mentioned one of the ways of worship - meaning to say, bowing - but we are also prohibited from sacrificing to them, offering libations and burning incense [to them]. And one who has transgressed one of these and bowed, sacrificed, offered libations or burned incense is liable for stoning. And the language of the Mekhilta (Mekhilta d'Rabbi Yishmael 22:19) is, "'One who sacrifices to gods shall be proscribed' (Exodus 22:19) - we have [thus] heard the punishment. From where [do we know] the prohibition? [Hence] we learn to say, 'You shall not bow to them and you shall not worship them.' Sacrifice was included (in serving), and it was singled out to teach [that] just as sacrificing is distinctive, in that we worship the Heavens in a similar way and one is liable for it, whether he worships it or he does not not worship it - so too, one is liable for all the ways that are similar to how we worship the Heavens, whether he worships it or he does not not worship it." And the content of this statement is that these four types of worship - being bowing, sacrificing, offering libations and burning incense - through which we have been commanded that we worship God, may He be blessed: Anyone who worships an idol through one of them is liable for stoning, even if this is not one of the ways of worshipping this thing that was worshipped. And that is what is called, not in the way of its worship. [Yet] since he worshipped in one of these ways, he is liable for stoning if he was volitional; excision if the court did not know about him or they did not execute the punishment; or to bring a sacrifice if he was inadvertent. And likewise when one accepts something as a god in a way of accepting. And this prohibition has already been repeated - meaning to say, the prohibition of their worship through one of these four ways, and even [when] it is not in its way. And that is His, may He be exalted, saying, "And that they may offer their sacrifices no more to the goats" (Leviticus 17:7). And the language of the Sifra (Sifra, Acharei Mot, Chapter 9:8) is, "'Goats,' is nothing other than demons." And in the Gemara, Zevachim (Zevachim 106a), it is explained, however, that this negative commandment is with slaughtering to the idol, even if the slaughtering is not the way of its worship. They said, "From where [do we know about] one who slaughters an animal as an offering to Mercury, that he is liable (even though this is not its way of worship)? As it is stated, 'And that they may offer their sacrifices no more.' If its content is not [applied to] in its way [of worship], as [that is already derived from] its being written, 'How do these nations serve' (Deuteronomy 12:30); then apply its content to [worshipping] not in its way." And one who transgresses it volitionally [gets] excision and stoning - as we said - and must bring a sacrifice if it was inadvertent. And the language of Scripture is, "One who sacrifices to gods shall be proscribed." And the laws of this commandment have already been explained in the seventh chapter of Sanhedrin.
