Sorry, didn’t see your question till now. I don’t remember word for word what that mechaneches said, but the general idea was that somehow, being thoroughly familiar with meforshim on various hebrew subjects gives the girls the chizuk and inspiration they need to be ehrliche, nurturing mothers and wives.
Nowhere in the article, however, was there an explanation for how exactly knowledge of a deeper pshat on a posuk in Nach with help anyone be a better mother/wife. So, honestly, I don’t get it.
