12 For I will go through the land of Egypt in that night, and will smite all the firstborn in the land of Egypt, both man and beast; and against all the gods of Egypt I will execute judgments: I am the Lord.
13 And the blood shall be to you for a token upon the houses where ye are: and when I see the blood, I will pass over you, and there shall no plague be upon you to destroy you, when I smite the land of Egypt.
14 And this day shall be unto 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 whosoever eateth leavened bread from the first day until the seventh day, that soul shall be cut off from Israel.
16 And in the first day there shall be to you an holy convocation, and in the seventh day an holy convocation; no manner of work shall be done in them, save that which every man must eat, that only may be done of you.
17 And ye shall observe the feast of unleavened bread; for in this selfsame day have I brought your hosts out of the land of Egypt: therefore shall ye observe this day throughout your generations by an ordinance for ever.
18 In the first month, on the fourteenth day of the month at even, ye shall eat unleavened bread, until the one and twentieth day of the month at even.
