Deuteronomy 12:31-32

Darby Translation

³¹ Thou shalt not do so to Jehovah thy God; for every [thing that is] abomination to Jehovah, which he hateth, have they done unto their gods; for even their sons and their daughters have they burned in the fire to their gods.

³² Everything that I command you, ye shall take heed to do it; thou shalt not add thereto, nor take from it.
