Shemot 12:3-6 Orthodox Jewish Bible (OJB)
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.
5 Your seh (lamb [see Yeshayah 53:7]) shall be tamim (without blemish), a zachar (male) within its first year; ye shall take it out from the sheep, or from the goats;
6 And it will be with you for mishmeret (examination, checking for blemishes) up until the fourteenth day of the same month; and kol Kehal Adat Yisroel shall slaughter (shachat) it in the afternoon [before dark].
