Exodus 12:15-18 - The Festival Of Unleavened Bread

¹⁵ Seven days, unleavened cakes, shall ye eat, surely, on the first day, shall ye put away leaven, out of your houses, - for whosoever eateth what is leavened, then shall that soul be cut off out of Israel, from the first day, unto the seventh day. ¹⁶ Both on the first day, a holy convocation, and on the seventh day - a holy convocation, shall there be to you, - no work, shall be done therein, save only what must be eaten by every soul, that alone, shall be done by you.

¹⁷ So then ye shall observe the unleavened cakes, because on this self-same day, brought I forth your hosts out of the land of Egypt, - so then ye shall observe this day to your generations, as a statute age-abiding, ¹⁸ In the first month, on the fourteenth day of the month in the evening, shall ye eat unleavened cakes, - until the one-and-twentieth day of the month in the evening,
