Mortar : (Heb. homer), cement of lime and sand (Genesis 11:3; Exodus 1:14); also potter's clay (Isaiah 41:25; Nahum 3:14). Also Heb. 'aphar, usually rendered "dust," clay or mud used for cement in building (Leviticus 14:42,45).
Mortar for pulverizing (Proverbs 27:22) grain or other substances by means of a pestle instead of a mill. Mortars were used in the wilderness for pounding the manna (Numbers 11:8). It is commonly used in Palestine at the present day to pound wheat, from which the Arabs make a favourite dish called kibby.
