Shemot 12:2-4

Orthodox Jewish Bible

² Hachodesh hazeh (this month) shall be unto you the beginning of months; it shall be the first month of the year to you.

³ Speak ye unto kol Adat Yisroel, saying, In the tenth day of this month they shall take to them every man a seh (lamb [see Yeshayah 53:7]), according to the bais avot, a seh for each bais;

⁴ And if the household be too small for the seh (lamb [see Yeshayah 53:7]), let him and his neighbor next unto his bais take according to the number of the nefashot; every ish according to what he eats shall make up your count for the seh.
