For seven days you shall eat unleavened bread, but on the first day you shall remove dough with yeast from your houses; for whoever eats anything with yeast from the first day until the seventh day, that person shall be cut off from Israel.

For seven days there shall be no dough with yeast found in your houses; for whoever eats anything with yeast, that person shall be cut off from the congregation of Israel, whether he is a stranger or a native of the land.

So the people took their dough before it was leavened, with their kneading bowls bound up in the clothes on their shoulders.

And they baked the dough which they had brought out of Egypt into cakes of unleavened bread. For it had no yeast, since they were driven out of Egypt and could not delay, nor had they prepared any provisions for themselves.

Unleavened bread shall be eaten throughout the seven days; and nothing with yeast shall be seen among you, nor shall any dough with yeast be seen among you in all your borders.
