"O you who have believed, indeed, among your wives and your children are enemies to you, so beware of them. But if you pardon and overlook and forgive - then indeed, Allah is Forgiving and Merciful."
Zawj زوج means spouse and not only wife. The translation which you are referring to is not accurate. It should be (O believers, some of your spouses and children are enemies to you, so beware of them) 64:14.
