Pr 31:23 Her husband is known in the gates, when he sitteth among the elders of the land.
Do you find it unusual that in these verses about a virtuous woman we find one about her husband?
If you think about it, in earlier verses it mentioned him and how she did only good to him.
It really isn't unusual that he was well known where her worked. He would not be able to devote the time to his work that was necessary for him to do the best job he could if she didn't do all a virtuous woman is called to do every day.
While the husband has been called by God to be the leader of the home, and yes even if he isn't saved, we are to have him lead, but not into sin, God has called us to be a help and not a hindrance to him in all he has been called to do in leading the family.
