And the people went about, and gathered it, and ground it in mills, or beat it in a mortar, and baked it in pans, and made cakes of it: and the taste of it was as the taste of fresh oil.
Proverbs 27:22
Though thou shouldest bray a fool in a mortar among wheat with a pestle, yet will not his foolishness depart from him.
