Deuteronomy 7
2 Ref and when Jehovah thy God shall deliver them up before thee, and thou shalt smite them; then thou shalt utterly destroy them: thou shalt make no covenant with them, nor show mercy unto them;
3 Ref neither shalt thou make marriages with them; thy daughter thou shalt not give unto his son, nor his daughter shalt thou take unto thy son.
4 Ref For he will turn away thy son from following me, that they may serve other gods: so will the anger of Jehovah be kindled against you, and he will destroy thee quickly.
5 Ref But thus shall ye deal with them: ye shall break down their altars, and dash in pieces their pillars, and hew down their Asherim, and burn their graven images with fire.
