Deuteronomy 12:32 In-Context

30 take heed to thyself that thou seek not to follow them after they are destroyed before thee, saying, How do these nations act towards their gods? I will do likewise.
31 Thou shalt not do so to thy God; for they have sacrificed to their gods the abominations of the Lord which he hates, for they burn their sons and their daughters in fire to their gods.
32 Every word that I command you this day, it shalt thou observe to do: thou shalt not add to it, nor diminish from it.
