Exodus
Chapters 12:1-4
Revised Version 1885
1And the Lord spake unto Moses and Aaron in the land of Egypt, saying,
2This month shall be unto you the beginning of months: it shall be the first month of the year to you.
3Speak ye unto all the congregation of Israel, saying, In the tenth day of this month they shall take to them every man a lamb, according to their fathers' houses, a lamb for an household:
4and if the household be too little for a lamb, then shall he and his neighbour next unto his house take one according to the number of the souls; according to every man's eating ye shall make your count for the lamb.
