Exodus 12:7 KJV

5Your lamb shall be without blemish, a male of the first year: ye shall take it out from the sheep, or from the goats:

6And ye shall keep it up until the fourteenth day of the same month: and the whole assembly of the congregation of Israel shall kill it in the evening.

7And 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.

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

9Eat not of it raw, nor sodden at all with water, but roast with fire; his head with his legs, and with the purtenance thereof.
