Exodus 12:17-19

Common English Bible

¹⁷ You should observe the Festival of Unleavened Bread, because on this precise day I brought you out of the land of Egypt in military formation. You should observe this day in every generation as a regulation for all time. ¹⁸ In the first month, from the evening of the fourteenth day until the evening of the twenty-first day, you should eat unleavened bread. ¹⁹ For seven days no yeast should be found in your houses because whoever eats leavened bread will be cut off from the Israelite community, whether the person is an immigrant or a native of the land.
