Exodus 12:19-20

New King James Version

¹⁹ For ^(A)seven days no leaven shall be found in your houses, since whoever eats what is leavened, that same person shall be cut off from the congregation of Israel, whether he is a stranger or a native of the land. ²⁰ You shall eat nothing leavened; in all your dwellings you shall eat unleavened bread.’ ”
