Deuteronomy 12:31-32 King James 2000 (KJ2000)

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

32. Whatsoever thing I command you, observe to do it: you shall not add thereto, nor take away from it.
