'Wafers' in the Bible

‘Now when you bring an offering of a grain offering baked in an oven, it shall be unleavened cakes of fine flour mixed with oil, or unleavened wafers spread with oil.

If he offers it by way of thanksgiving, then along with the sacrifice of thanksgiving he shall offer unleavened cakes mixed with oil, and unleavened wafers spread with oil, and cakes of well stirred fine flour mixed with oil.
