Seven days shall ye eat unleavened bread; even the first day ye shall put away leaven out of your houses: for whosoever eateth leavened bread from the first day until the seventh day, that soul shall be cut off from Israel.
For one week, eat only bread without yeast. On the first day, remove all yeast from your home. If someone eats yeasted bread between the first and seventh day, they will be expelled from Israel.
