Exodus 29:2-3, 23

Then, using choice wheat flour and no yeast, make loaves of bread, thin cakes mixed with olive oil, and wafers spread with oil. Place them all in a single basket, and present them at the entrance of the Tabernacle, along with the young bull and the two rams.

Then take one round loaf of bread, one thin cake mixed with olive oil, and one wafer from the basket of bread without yeast that was placed in the LORD’s presence.
