Even someone who was a servant, in the ancient world, was expected to speak up and warn his master if he was doing something stupid.
In Jewish culture, wives were supposed to be enterprising, clever, always looking out for a way to help out the family or make life better for people outside the family who needed help. They ran stuff and had their own businesses; the husband did oversight when needed, and only then. That is why we have stuff like the Valiant Woman passage in Proverbs, or the story of Abigail.
The idea that God made woman from the man’s side, because she was made to stand beside him, and not be under or over him, is an ancient interpretation. The saying that “man is the head of the family but woman is the neck,” is almost as old.
When husbands use their authority properly and lightly, unless the situation is important, wives can know when they mean it.
If wives do not bother husbands about unimportant matters that are well within wifely authority, and they act wisely and in a trustworthy way, husbands will know they can trust their wives.
