Exodus 29:2

and unleavened bread , unleavened cakes mixed with oil , and unleavened wafers smeared with oil . You shall make them of fine wheat flour .

And from the finest wheat flour make round loaves without yeast, thick loaves without yeast and with olive oil mixed in, and thin loaves without yeast and brushed with olive oil.

And unleavened bread, and cakes unleavened tempered with oil, and wafers unleavened anointed with oil : of wheaten flour shalt thou make them.
