Exodus 12:10-16 AMP

10 You shall let nothing of the meat remain until the morning; and the bones and unedible bits which remain of it until morning you shall burn with fire.

11 And you shall eat it thus: [as fully prepared for a journey] your loins girded, your shoes on your feet, and your staff in your hand; and you shall eat it in haste. It is the Lord's Passover.

12 For 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 [proving their helplessness]. I am the Lord.

13 The blood shall be for a token or sign to you upon [the doorposts of] the houses where you are, [that] when I see the blood, I will pass over you, and no plague shall be upon you to destroy you when I smite the land of Egypt. [I Cor. 5:7; Heb. 11:28.]

14 And this day shall be to you for a memorial. You shall keep it as a feast to the Lord throughout your generations, keep it as an ordinance forever.

15 [In celebration of the Passover in future years] seven days shall you eat unleavened bread; even the first day you shall put away leaven [symbolic of corruption] out of your houses; for whoever eats leavened bread from the first day until the seventh day, that person shall be cut off from Israel.

16 On the first day you shall hold a solemn and holy assembly, and on the seventh day there shall be a solemn and holy assembly; no kind of work shall be done in them, save [preparation of] that which every person must eat–that only may be done by you.
