Exodus 12:4 WEB

²  'This month shall be to you the beginning of months. It shall be the first month of the year to you.

³  Speak to all the congregation of Israel, saying, 'On the tenth day of this month, they shall take to them every man a lamb, according to their fathers' houses, a lamb for a household;

⁴  and if the household be too little for a lamb, then he and his neighbor next to his house shall take one according to the number of the souls; according to what everyone can eat you shall make your count for the lamb.

⁵  Your lamb shall be without blemish, a male a year old. You shall take it from the sheep, or from the goats:

⁶  and you shall keep it until the fourteenth day of the same month; and the whole assembly of the congregation of Israel shall kill it at evening.
