A grain much cultivated in Egypt (Ex. 9:31) and in Palestine (Lev. 27:16; Deut. 8:8). It was usually the food of horses (1 Kings 4:28). Barley bread was used by the poorer people (Judg. 7:13; 2 Kings 4:42). Barley of the first crop was ready for the harvest by the time of the Passover, in the middle of April (Ruth 1:22; 2 Sam. 21:9). Mention is made of barley-meal (Num. 5:15). Our Lord fed five thousand with "five barley loaves and two small fishes" (John 6:9).
