Charles Ellicott Commentary Leviticus 2:4

"And when thou offerest an oblation of a meal-offering baken in the oven, it shall be unleavened cakes of fine flour mingled with oil, or unleavened wafers anointed with oil." — Leviticus 2:4 (ASV)

A meat offering baked in the oven—this was the second kind of meat offering and consisted of preparations baked with oil in the oven, in a pan, or cooked in a pot (Leviticus 2:4–10). The oven described is probably the portable pot, open at the top, about three feet high, and liable to be broken (Leviticus 11:35), which is still used in the East for making bread and cakes.

After the vessel is thoroughly heated, the dough—made into large, thin, oval cakes resembling pancakes or Scottish oatcakes—is dexterously thrown against its sides. The opening above is then covered, and the bread is completely baked in a few minutes. Although the bread is soft when first taken out and can be rolled up like paper, it hardens and becomes crisp when kept.
