'Household' in the Bible

Tell the whole community of Israel that on the tenth day of this month they must each select an animal of the flock according to their fathers’ households, one animal per household.

If the household is too small for a whole animal, that person and the neighbor nearest his house are to select one based on the combined number of people; you should apportion the animal according to what each person will eat.

If a foreigner resides with you and wants to celebrate the Lord’s Passover, every male in his household must be circumcised, and then he may participate; he will become like a native of the land. But no uncircumcised person may eat it.
