Deuteronomy 7:2-4

2and when Jehovah thy GodH430 shall deliver them up before thee, and thou shalt smite them; then thou shalt utterly destroyH2763 them: thou shalt makeH5414 no covenantH1285 with them, nor show mercy unto them;

3neither shalt thou makeH5414 marriages with them; thy daughterH1323 thou shalt not giveH5414 unto his sonH1121, nor his daughterH1323 shalt thou takeH3947 unto thy sonH1121.

4For he will turnH5493 awayH5493 thy sonH1121 from following me, that they may serveH5647 otherH312 godsH430: so will the angerH639 of Jehovah be kindled against you, and he will destroyH8045 thee quicklyH4118.
