'Unleavened' in the Bible

And when thou offerest an oblation of a meal-offering baken in the oven, it shall be unleavened cakes of fine flour mingled with oil, or unleavened wafers anointed with oil.

And if thy oblation be a meal-offering of the baking-pan, it shall be of fine flour unleavened, mingled with oil.

If he offer it for a thanksgiving, then he shall offer with the sacrifice of thanksgiving unleavened cakes mingled with oil, and unleavened wafers anointed with oil, and cakes mingled with oil, of fine flour soaked.

Take Aaron and his sons with him, and the garments, and the anointing oil, and the bullock of the sin-offering, and the two rams, and the basket of unleavened bread;

and out of the basket of unleavened bread, that was before Jehovah, he took one unleavened cake, and one cake of oiled bread, and one wafer, and placed them on the fat, and upon the right thigh:

And on the fifteenth day of the same month is the feast of unleavened bread unto Jehovah: seven days ye shall eat unleavened bread.
