'Unleavened Bread' in the Bible

And the rest of it Aaron and his sons shall eat. It shall be eaten with unleavened bread in the holy place. They shall eat it in the court of the tabernacle of the congregation.

Take Aaron, and his sons with him, and the garments, and the anointing oil, and a young bull for the sin offering, and two rams, and a basket of unleavened bread.

And he took one unleavened cake out of the basket of unleavened bread that was before Jehovah, and a cake of oiled bread, and one wafer, and put them on the fat, and on the right shoulder.

and on the fifteenth day of the same month is the Feast of Unleavened Bread to Jehovah. You must eat unleavened bread seven days.
