Exodus 12:7-13 And they shall take of the blood, and strike it on the two side posts and on the upper door post of the houses, wherein they shall eat it.

KJV⁽ⁱ⁾ ⁷ And they shall take of the blood, and strike it on the two side posts and on the upper door post of the houses, wherein they shall eat it. ⁸ And they shall eat the flesh in that night, roast with fire, and unleavened bread; and with bitter herbs they shall eat it. ⁹ Eat not of it raw, nor sodden at all with water, but roast with fire; his head with his legs, and with the purtenance thereof. ¹⁰ And ye shall let nothing of it remain until the morning; and that which remaineth of it until the morning ye shall burn with fire. ¹¹ And 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. 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: 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 the plague shall not be upon you to destroy you, when I smite the land of Egypt.
