Deuteronomy 7:4 in the King James Version
For they will turn away thy son from following me, that they may serve other gods: so will the anger of the LORD be kindled against you, and destroy thee suddenly.
Context
3 You shall not make marriages with them. You shall not give your daughter to his son, nor shall you take his daughter for your son.
4 For that would turn away your sons from following me, that they may serve other gods. So the LORD’s anger would be kindled against you, and he would destroy you quickly.
5 But you shall deal with them like this: you shall break down their altars, dash their pillars in pieces, cut down their Asherah poles, and burn their engraved images with fire.
