Exodus 12:18-20

Common English Bible

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. ²⁰ You should not eat anything made with yeast in all your settlements. You should eat only unleavened bread.”
