Job 31:10

“[Then] let my wife grind unto another, etc.] Which some understand literally, of her being put to the worst of drudgery and slavery, to work at a mill, and grind corn for the service of a stranger, and be exposed to the company of the meanest of persons, and to their insults and abuses; as we find such as were taken captives and made prisoners by an enemy were put unto, as Samson, (<071621>Judges 16:21); and it may be observed, that to grind in a mill was also the work of women, (<021105>Exodus 11:5 <402441>Matthew 24:41); as it was in early times; Homer f1127 speaks of it as in times before him; but others take the words in a figurative sense, as if he imprecated that she lie with another…”
