Exodus 12:8-15

8And they shall eat the flesh in that night, roasted with fire, and unleavened bread; and with bitter herbs they shall eat it.

9Eat not of it raw, nor boiled at all with water, but roasted with fire; its head with its legs, and with its inward parts.

10And ye shall let nothing of it remain till the morning; and that which remaineth of it till the morning ye shall burn with fire.

11And thus shall ye eat it; with your loins girded, your shoes on your feet, and your staff in your hand; and ye shall eat it in haste: it is the LORD’S passover.

12For I will pass through the land of Egypt this 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 judgment: I am the LORD.1

13And 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 the plague shall not be upon you to destroy you, when I smite the land of Egypt.2

14And 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.

15Seven 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.
