Leviticus 8:2, 26, 31

“Bring Aaron and his sons, along with their sacred garments, the anointing oil, the bull for the sin offering, the two rams, and the basket of bread made without yeast

On top of these he placed a thin cake of bread made without yeast, a cake of bread mixed with olive oil, and a wafer spread with olive oil. All these were taken from the basket of bread made without yeast that was placed in the LORD’s presence.
