TSK · Exodus 29:2

They will eat the meat the same night; they will eat it roasted over the fire with bread made without yeast and with bitter herbs.

Processed Grain Offerings“‘When you present an offering of grain baked in an oven, it must be made of choice wheat flour baked into unleavened loaves mixed with olive oil or unleavened wafers smeared with olive oil.

A continual fire must be kept burning on the altar. It must not be extinguished.

Every grain offering, whether mixed with olive oil or dry, belongs to all the sons of Aaron, each one alike.

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

and a basket of bread made without yeast, cakes of fine flour mixed with olive oil, wafers made without yeast and smeared with olive oil, and their grain offering and their drink offerings.

Clean out the old yeast so that you may be a new batch of dough– you are, in fact, without yeast. For Christ, our Passover lamb, has been sacrificed.
