The Lord said to Moses and Aaron in the land of Egypt:
This month shall mark for you the beginning of months; it shall be the first month of the year for you.
Tell the whole congregation of Israel that on the tenth of this month they are to take a lamb for each family, a lamb for each household.
If a household is too small for a whole lamb, it shall join its closest neighbor in obtaining one; the lamb shall be divided in proportion to the number of people who eat of it.
Your lamb shall be without blemish, a year-old male; you may take it from the sheep or from the goats.
You shall keep it until the fourteenth day of this month; then the whole assembled congregation of Israel shall slaughter it at twilight.
