Easton's Bible Dictionary (1897)
Cakes made of wheat or barley were offered in the temple. They were salted, but unleavened (Ex. 29:2; Lev. 2:4). In idolatrous worship thin cakes or wafers were offered “to the queen of heaven” (Jer. 7:18; 44:19). Pancakes are described in 2 Sam. 13:8, 9. Cakes mingled with oil and baked in the oven are mentioned in Lev. 2:4, and “wafers unleavened anointed with oil,” in Ex. 29:2; Lev. 8:26; 1 Chr. 23:29. “Cracknels,” a kind of crisp cakes, were among the things Jeroboam directed his wife to take with her when she went to consult Ahijah the prophet at Shiloh (1 Kings 14:3).
Such hard cakes were carried by the Gibeonites when they came to Joshua (9:5, 12). ” It is rendered “cracknels” in 1 Kings 14:3. The ordinary bread, when kept for a few days, became dry and excessively hard. The Gibeonites pointed to this hardness of their bread as an evidence that they had come a long journey. We read also of honey-cakes (Ex. 16:31), “cakes of figs” (1 Sam. 25:18), “cake” as denoting a whole piece of bread (1 Kings 17:12), and “a [round] cake of barley bread” (Judg. 7:13).
In Lev. 2 is a list of the different kinds of bread and cakes which were fit for offerings.
