Deuteronomy 12:30-32 World English Bible (WEB)

30. be careful that you are not ensnared to follow them, after that they are destroyed from before you; and that you not inquire after their gods, saying, “How do these nations serve their gods? I will do likewise.”

31. You shall not do so to Yahweh your God; for every abomination to Yahweh, which he hates, have they done to their gods; for they even burn their sons and their daughters in the fire to their gods.

32. Whatever thing I command you, that you shall observe to do. You shall not add to it, nor take away from it.
