Exodus 12:15–20

¹⁵Seven days shall ye eat unleavened bread: on the very first day ye shall put away leaven out of your houses; for whoever eateth leavened bread from the first day until the seventh day—that soul shall be cut off from Israel. ¹⁶And on the first day ye shall have a holy convocation, and on the seventh day a holy convocation: no manner of work shall be done on them, save what is eaten by every person—that only shall be done by you. ¹⁷And ye shall keep the feast of unleavened bread; for in this same day have I brought your hosts out of the land of Egypt; and ye shall keep this day in your generations as an ordinance for ever. ¹⁸In the first month, on the fourteenth day of the month, in the evening, ye shall eat unleavened bread until the one and twentieth day of the month in the evening. ¹⁹Seven days shall there be no leaven found in your houses; for whoever eateth what is leavened—that soul shall be cut off from the assembly of Israel, whether he be a sojourner, or born in the land. ²⁰Ye shall eat nothing leavened: in all your dwellings shall ye eat unleavened bread.
