Thou shalt not do so unto the LORD thy God: for every abomination to the LORD, which he hateth, have they done unto their gods; for even their sons and their daughters they have burnt in the fire to their godsWhat thing soever I command you, observe to do it: thou shalt not add thereto, nor diminish from it."
