'Family' in the Bible

“If brothers are living together and one of them dies without a son, the widow of the deceased shall not be married outside the family to a stranger. Her husband’s brother shall be intimate with her after taking her as his wife and perform the duty of a husband’s brother to her.

In Israel his [family] name shall be, ‘The house of him whose sandal was removed.’

so that there will not be among you a man or woman, or family or tribe, whose heart turns away today from the Lord our God, to go and serve the [false] gods of these nations; so that there will not be among you a root [of idolatry] bearing poisonous fruit and wormwood (bitterness).
