Exodus 12:18–20

In the first month, from the fourteenth day of the month at evening, you shall eat unleavened bread until the twenty-first day of the month at evening. For seven days no leaven is to be found in your houses. If anyone eats what is leavened, that person will be cut off from the congregation of Israel, whether he is a sojourner or a native of the land. You shall eat nothing leavened; in all your dwelling places you shall eat unleavened bread.”

In the first month you are to eat bread made without yeast, from the evening of the fourteenth day until the evening of the twenty-first day. For seven days no yeast is to be found in your houses. And anyone, whether foreigner or native-born, who eats anything with yeast in it must be cut off from the community of Israel. Eat nothing made with yeast. Wherever you live, you must eat unleavened bread.”

The bread you eat must be made without yeast from the evening of the fourteenth day of the first month until the evening of the twenty-first day of that month. During those seven days, there must be no trace of yeast in your homes. Anyone who eats anything made with yeast during this week will be cut off from the community of Israel. These regulations apply both to the foreigners living among you and to the native-born Israelites. During those days you must not eat anything made with yeast. Wherever you live, eat only bread made without yeast.”

On the first day, on the fourteenth day of the month, in the evening, you will eat unleavened bread until the evening of the twenty-first day of the month. For seven days yeast must not be found in your houses, because anyone eating food with yeast will be cut off from the community of Israel—whether an alien or a native of the land. You will eat no food with yeast; in all of your dwellings you will eat unleavened bread.”

In the first month, on the fourteenth day of the month at even, ye shall eat unleavened bread, until the one and twentieth day of the month at even. 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. Ye shall eat nothing leavened; in all your habitations shall ye eat unleavened bread.
