Isaiah 47:2

Take the millstones, those of the hand-mill, as turned by female slaves, and grind meal, the grain being fed in through the center opening above and ground to flour by the revolving of the upper stone; uncover thy locks, taking off the veil, probably together with the plaite(l hair, as worn by Oriental women, its removal being considered a mark of the deepest degradation, make bare the leg, removing the long outer garment worn especially by women of rank, uncover the thigh, gathering up even the inner garment, pass over the rivers, like a slave girl being taken into captivity.
