What is the mantle of a wife?

I must confess, the phrase 'mantle of a wife' seems rather archaic and unusual in modern parlance. Could you elaborate on its intended meaning within the context you've mentioned? It seems to carry a certain weight and significance, perhaps referencing a role or responsibility unique to a married woman. Is it a reference to domestic duties, emotional support, or perhaps a more symbolic representation of her status? I'm genuinely curious to understand this expression and how it might be interpreted in today's society.
