And the Lord said to Moses and Aaron in the land of Egypt:
This month shall be to you the beginning of months; it shall be the first in the months of the year.
Speak ye to the whole assembly of the children of Israel, and say to them: On the tenth day of this month let every man take a lamb by their families and houses.
But if the number be less than may suffice to eat the lamb, he shall take unto him his neighbour that joineth to his house, according to the number of souls which may be enough to eat the lamb.
And it shall be a lamb without blemish, a male, of one year; according to which rite also you shall take a kid.
And you shall keep it until the fourteenth day of this month; and the whole multitude of the children of Israel shall sacrifice it in the evening.
