Thematic Bible: During the feast of passover

Seven days ye shall eat unleavened; wholly in the first day shall ye turn away leaven in your houses; for all eating leavened and that soul was destroyed from Israel from the first day even to the seventh day. And in the first day a calling of holiness, and in the seventh day a calling of holiness shall be to you; every service shall not be done in them only what shall be eaten by every soul; this only shall be done by you. And ye watched the unleavened; for in this self-same day I brought forth your armies out of the land of Egypt and watch ye this day for your generations a law forever. read more.
In the first, in the fourteenth day of the month, in the evening, ye shall eat unleavened till the one and twentieth day of the month in the evening. Seven days leaven shall not be found in your houses; for all eating from the leavened, that soul shall be destroyed from the assembly of Israel, for the sojourner or for the native of the land. All leavened ye shall not eat: in all your dwellings ye shall eat unleavened.
