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). They described their bread as "mouldy;" but the
Hebrew word "nikuddim", here used, ought rather to be rendered
"hard as biscuit." 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.
