"You shall not profane My holy name, but I will be sanctified among the sons of Israel; I am the LORD who sanctifies you, who brought you out from the land of Egypt, to be your God; I am the LORD." (Leviticus 22:32-33)
This negative commandment literally tells us not to "profane" G-d's holy name. Profane means "marked by contempt or irreverence for what is sacred".
"You shall utterly destroy all the places where the nations whom you shall dispossess serve their gods, on the high mountains and on the hills and under every green tree. You shall tear down their altars and smash their sacred pillars and burn their Asherim with fire, and you shall cut down the engraved images of their gods and obliterate their name from that place. You shall not act like this toward the LORD your God." (Deuteronomy 12:2-4)
This negative commandment literally says that we should not destroy the places where we serve G-d, tear down G-d's altar, or obliterate G-d's name. These were the things Israel was commanded to do in regards to gods of the nations they dispossessed when they entered the promised land.
