'Family' in the Bible

Then the father realized that this was the very hour when Jesus had told him, "Your son will live." So he himself believed, along with his whole family.

But some were saying, "The Messiah doesn't come from Galilee, does he? Doesn't the Scripture say that the Messiah is from David's family and from Bethlehem, the village where David lived?"

The slave does not remain in the family forever, but the son remains forever.
