Ephesians 6:4 says not to provoke children to anger. What exactly does that mean and in a situation with a friend’s parent, who says mean things to her, how can I explain to her father that that isn’t the way to do things.

First sorry if I’m not quite clear in describing the situation or exactly what I mean towards this question. Her father acts out in anger himself towards her situation in life, being an alcoholic and such and struggling to love herself. I want to help them but don’t know what to do.

With this verse, what is expected of a father to his children? How exactly does one NOT provoke his children to anger? And what can I say to her father to help him understand his harsh words are causing her to “hate” her father. I’m doing my best to try to get her to understand our Heavenly Father is the perfect dad we all want and need. She’s open to the gospel, somewhat, which makes me happy, as I truly care for her and her soul. She’s in a bad place right now and constantly on the verge of being homeless. Which WONT help her situation at all. Maybe she needs to hit rock bottom? Anyways, again apologize if I’m being confusing in my questions. Hope I can get some answers. Thanks.
