'Family' in the Bible

And Joseph also went up from Galilee, out of the city of Nazareth, into Judaea, to the city of David, which is called Bethlehem, because he was of the house and family of David;

from whom every family in heaven and on earth is named,

But if any widow hath children or grandchildren, let them learn first to show piety towards their own family, and to requite their parents: for this is acceptable in the sight of God.
