Exodus 12:18-20

International Standard Version

¹⁸ In the first month, from the evening of the fourteenth day of the month until the evening of the twenty-first day of the month, you are to eat unleavened bread. ¹⁹ For seven days leaven is not to be found in your houses. Indeed, any person who eats anything leavened, is to be cut off from the congregation of Israel, whether an alien or a native of the land. ²⁰ You are not to eat what is leavened. You are to eat unleavened bread in all your settlements.’”
