Deuteronomy 12:29-32

29When Jehovah thy GodH430 shall cutH3772 off the nationsH1471 from before thee, whither thou goest in to dispossessH3423 them, and thou dispossessest them, and dwellest in their landH776; 30takeH8104 heedH8104 to thyself that thou be not ensnared to follow them, after that they are destroyedH8045 from before thee; and that thou inquire not after their godsH430, sayingH559, HowH349 do these nationsH1471 serveH5647 their godsH430? even soH3651 will I do likewise. 31Thou shalt not do soH3651 unto Jehovah thy GodH430: for every abominationH8441 to Jehovah, which he hateth, have they done unto their godsH430; for even their sonsH1121 and their daughtersH1323 do they burnH8313 in the fireH784 to their godsH430.

32What thing soever I command you, that shall ye observe to do: thou shalt not add thereto, nor diminish from it.
