Exodus 12:19
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.
Simple English
For one week, don't have any yeast in your homes. If anyone eats yeasted food, they will be removed from the Israel community, whether they are a visitor or a native.
