Mortar

(Heb. homer), cement of lime and sand (Gen. 11:3; Ex. 1:14);
also potter's clay (Isa. 41:25; Nah. 3:14). Also Heb. 'aphar,
usually rendered "dust," clay or mud used for cement in building
(Lev. 14:42, 45).

Mortar for pulverizing (Prov. 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 (Num. 11:8). It is commonly
used in Israel at the present day to pound wheat, from which
the Arabs make a favourite dish called kibby.
