In 2 Samuel 12, David is told that because of his sin with Bathsheba (and Uriah), the sword will never leave his house. Bible students know what that means. For the rest of his life, David would watch as his family tore itself apart, from sons raping half sisters, to sons leading coups, to brothers attempting to steal the throne from each other, and more.
Some families today are like that (minus the violence). A lot of people grew up in an environment that is tense, angry, backbiting, and overall not pointed towards God.
If that's you and you're a parent, you have one job: Get the sword out of your house.
