What have they seen in your house? (2 Kings 20:15). In the news last week was a house in California with children being starved and held captive by the parents.
That makes this question relevant. No one in the neighborhood supposedly knew what was going on. Does that mean that no one in the neighborhood had been inside that house? Though the years, we have heard some horror stories about things happening inside houses and neighbors not knowing the evil existing right under their noses.
The word of the Lord teaches men to be neighborly because living beside another carries a lot of responsibly (Proverbs 3:29). One day it may come down to a matter of life or death. That neighbor might be the lifeline if you are having a heart attack or stroke, etc. Do you want to be involved in evil deeds and cannot have others come inside lest they see? Do you want to continue being unfriendly toward that neighbor? Think about this before the emergency arrives. But I suppose cases like the California house will continue and that is sad indeed. But if you are inspired to attempt to change things, great!
It’s a step in the right direction.
