Exodus 12:8-14

They are to eat the meat that night; they should eat it, roasted over the fire along with unleavened bread and bitter herbs.  Do not eat any of it raw or cooked in boiling  water, but only roasted  over fire #— #its head as well as its legs and inner organs. You must not leave any of it until morning;  any part of it left until morning you must burn. Here is how you must eat it: You must be dressed for travel,  your sandals on your feet, and your staff in your hand. You are to eat it in a hurry; it is the LORD’s Passover.  “I will pass through  the land of Egypt on that night and strike every firstborn male in the land of Egypt, both people and animals. I am the LORD; I will execute judgments against all the gods of Egypt.  The blood on the houses where you are staying will be a distinguishing mark for you; when I see the blood, I will pass over you. No plague will be among you to destroy you when I strike the land of Egypt. “This day is to be a memorial for you, and you must celebrate it as a festival to the LORD. You are to celebrate it throughout your generations as a permanent statute.
