For grinding corn, mentioned as used in the time of Abraham (Gen. 18:6). That used by the Hebrews consisted of two circular stones, each 2 feet in diameter and half a foot thick, the lower of which was called the “nether millstone” (Job 41:24) and the upper the “rider.” The upper stone was turned round by a stick fixed in it as a handle. There were then no public mills, and thus each family required to be provided with a hand-mill. The corn was ground daily, generally by the women of the house (Isa. 47:1, 2; Matt. 24:41). It was with the upper stone of a hand-mill that “a certain woman” at Thebez broke Abimelech’s skull (Judg. 9:53, “a piece of a millstone;” literally, “a millstone rider”, i.e., the “runner,” the stone which revolves. Comp. 2 Sam. 11:21). Millstones could not be pledged (Deut. 24:6), as they were necessary in every family.
Mill
Before there was flour at the store, there was the millstone: two heavy stones, with grain ground between them. The Law protected this daily tool, saying no one should “take the nether or the upper millstone to pledge,” since that took away a household’s bread. The mill also shows up in sorrow. Samson, blinded and bound, “did grind in the prison house.” And Jesus uses a millstone to warn how seriously God takes harm done to “these little ones that believe in me.” Three very different scenes, one humble object. Matthew 18 is the best place to begin.
