Serving them: Receive blessings when one treats them well
Not serving them: Receive curses when ill treated
Who they are: Women/wives
Why: It’s probably why the heathens usually elevate women as gods than men, especially when it comes to love, sex, fertility, fruitfulness, productivity, etc. which are all related to prayer
Reference: 1 Peter 3:7
Likewise, ye husbands, dwell with them according to knowledge, giving honour unto the wife, as unto the weaker vessel, and as being heirs together of the grace of life; that your prayers be not hindered.
Message: What Peter is saying is, “look, instead of serving these female deaf and dumb idols, respect your wives or women at home and whatever you’re seeking to do will not be hindered”.
