Exodus 12:3-8

3Tell the whole community of Israel, ‘In the tenth day of this month they each must take a lamb for themselves according to their families – a lamb for each household.

4If any household is too small for a lamb, the man and his next-door neighbor are to take a lamb according to the number of people – you will make your count for the lamb according to how much each one can eat.

5Your lamb must be perfect, a male, one year old; you may take it from the sheep or from the goats.

6You must care for it until the fourteenth day of this month, and then the whole community of Israel will kill it around sundown.

7They will take some of the blood and put it on the two side posts and top of the doorframe of the houses where they will eat it.

8They will eat the meat the same night; they will eat it roasted over the fire with bread made without yeast and with bitter herbs.
