Exodus 29:2-3, 23

and unleavened bread, unleavened cakes mixed with oil, and unleavened wafers smeared with oil. You shall make them of fine wheat flour. You shall put them in one basket and bring them in the basket, and bring the bull and the two rams.

and one loaf of bread and one cake of bread made with oil, and one wafer out of the basket of unleavened bread that is before the LORD.
