'Wafers' in the Bible

“When you present a grain offering baked in an oven, it must be made of fine flour, either unleavened cakes mixed with oil or unleavened wafers coated with oil.

If he presents it for thanksgiving, in addition to the thanksgiving sacrifice, he is to present unleavened cakes mixed with olive oil, unleavened wafers coated with oil, and well-kneaded cakes of fine flour mixed with oil.
