Exodus 12:16 WBT

¹⁴  And this day shall be to you for a memorial; and ye shall keep it a feast to the LORD throughout your generations: ye shall keep it a feast by an ordinance for ever.

¹⁵  Seven days shall ye eat unleavened bread; even the first day ye shall put away leaven out of your houses: for whoever eateth leavened bread, from the first day till the seventh day, that soul shall be cut off from Israel.

¹⁶  And in the first day [there shall be] a holy convocation, and in the seventh day there shall be a holy convocation to you: no manner of work shall be done in them, save [that] which every man must eat, that only may be done by you.

¹⁷  And ye shall observe [the feast of] unleavened bread; for in this same day have I brought your armies out of the land of Egypt: therefore shall ye observe this day in your generations by an ordinance for ever.

¹⁸  In the first [month], on the fourteenth day of the month at evening, ye shall eat unleavened bread, till the one and twentieth day of the month at evening.
