Exodus 12:4-6

Revised Standard Version Catholic Edition

⁴ and if the household is too small for a lamb, then a man and his neighbor next to his house shall take according to the number of persons; according to what each 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 this month, when the whole assembly of the congregation of Israel shall kill their lambs in the evening.^[a]
