That's why men with many wives typical give the inheritance to the children of the first wife: she's usually the best match. Anyone willing to marry him, after her, knew she would be sharing, and did it, anyway, as she isn't good enough to be that sort of man's First Wife. And the 13th wife is probably just someone he dragged home from the bar. 😂
