'Household' in the Bible

Now these are the names of the sons of Israel, who came into Egypt (every man and his household came with Jacob):

Speak 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 a household:

and if the household be too little for a lamb, then shall he and his neighbor 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.
