'Family' in the Bible

About his Son who, in the flesh, came from the family of David,

For those whom He has known beforehand He has also pre-destined to bear the likeness of His Son, that He might be the Eldest in a vast family of brothers;

For I have a desire to take on myself the curse for my brothers, my family in the flesh:

Show family affection to one another with brotherly love. Outdo one another in showing honor.

Greet Apelles, who has been approved by the Messiah. Greet those who belong to the family of Aristobulus.

Greet Herodion, my fellow Jew. Greet those in the family of Narcissus, who belong to the Lord.
