Variantly: What is the intent of "You shall now bow down"? (Exodus 22:19) "He who slaughters to a god shall be put to death — only to the L–rd alone" tells us of the punishment. Whence (do we derive) the exhortation? From "You shall not bow down."
Why Does the Torah Also Need a Separate Prohibition Against Bowing
Mekhilta Tractate Bachodesh 6:18
