Mill

A mill for grinding corn was 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. Compare 2 Sam. 11:21).

Millstones could not be pledged (Deut. 24:6), as they were necessary in every family.
