Isaiah 47:2

Take the millstones, and grind meal "Take the mill, and grind corn" - It was the work of slaves to grind the corn. They used hand-mills: water-mills were not invented till a little before the time of Augustus, (see the Greek epigram of Antipater, which seems to celebrate it as a new invention, Anthol. Cephalae, 653); wind-mills, not until long after. It was not only the work of slaves, but the hardest work; and often inflicted upon them as a severe punishment: -

Molendum in pistrino; vapulandum; habendae compedes .

Terent. Phorm. 2:1. 19.

Hominem pistrino dignum
