ADONAI spoke to Moshe and Aharon in the land of Egypt; he said,
"You are to begin your calendar with this month; it will be the first month of the year for you.
Speak to all the assembly of Isra'el and say, 'On the tenth day of this month, each man is to take a lamb or kid for his family, one per household -
except that if the household is too small for a whole lamb or kid, then he and his next-door neighbor should share one, dividing it in proportion to the number of people eating it.
Your animal must be without defect, a male in its first year, and you may choose it from either the sheep or the goats.
"'You are to keep it until the fourteenth day of the month, and then the entire assembly of the community of Isra'el will slaughter it at dusk.
