Thomas Aquinas, on Isa 47:2

“Take a millstone and grind meal: uncover thy shame, strip thy shoulder, make bare thy legs, pass over the rivers.”

“Second, as to the ignominy which they incurred: take a millstone, which was the work of servant girls, as if to say: you shall be a servant girl; or it signifies sexual intercourse, as in Judges 16:21 of Samson; uncover your shame, that is, your shameful members, either to the lust of your enemies or for crossing rivers on foot: I will change their glory into shame (Hos 4:7).”
