Exodus 12:3-5

New Century Version

³ Tell the whole community of Israel that on the tenth day of this month each man must get one lamb for the people in his house. ⁴ If there are not enough people in his house to eat a whole lamb, he must share it with his closest neighbor, considering the number of people. There must be enough lamb for everyone to eat. ⁵ The lamb must be a one-year-old male that has nothing wrong with it. This animal can be either a young sheep or a young goat.
