TSK · Exodus 13:7

Seven days shall there be no leaven found in your houses: for whosoever eateth that which is leavened, even that soul shall be cut off from the congregation of Israel, whether he be a stranger, or born in the land.

And they did eat of the old corn of the land on the morrow after the passover, unleavened cakes, and parched [corn] in the selfsame day.
