'Wafer' in the Bible

a basket of unleavened bread made from choice flour, cakes mixed with oil, a wafer of unleavened bread smeared with oil, along with grain and drink offerings.

Then the priest is to take the boiled shoulder of the ram, one cake of unleavened bread from the basket, and one wafer of unleavened bread. He is to place them in the hands of the Nazirite, after he himself has shaved his symbol of consecration.
