In biblical texts, particularly within the Old Testament accounts of the Exodus and wilderness wanderings, wafers referred to thin, unleavened cakes or breads baked without yeast. Most famously, they describe the physical form of manna—the miraculous divine sustenance provided to the Israelites—which was often compared in ancient descriptions to thin wafers made with honey or coriander seed. In various ritual sacrifices and priestly consecration ceremonies detailed in Leviticus and Exodus, unleavened bread wafers smeared or mixed with olive oil were also explicitly prescribed as holy offerings presented to the Lord.
