'Household' in the Bible

These are the names of the sons of Israel who entered Egypt -- each man with his household entered with Jacob:

A man from the household of Levi married a woman who was a descendant of Levi.

Tell the whole community of Israel, 'In the tenth day of this month they each must take a lamb for themselves according to their families -- a lamb for each household.

If any household is too small for a lamb, the man and his next-door neighbor are to take a lamb according to the number of people -- you will make your count for the lamb according to how much each one can eat.
