'Family' in the Bible

Saul answered, "Am I not a Benjamite, of the smallest of the tribes of Israel? And my family the least of all the families of the tribe of Benjamin? Why then do you speak to me like this?"

He brought the tribe of Benjamin near by their families; and the family of the Matrites was taken; and Saul the son of Kish was taken: but when they sought him, he could not be found.

David said to Saul, "Who am I, and what is my life, or my father's family in Israel, that I should be son-in-law to the king?"

If your father miss me at all, then say, 'David earnestly asked leave of me that he might run to Bethlehem his city; for it is the yearly sacrifice there for all the family.'

He said, 'Please let me go, for our family has a sacrifice in the city. My brother has commanded me to be there. Now, if I have found favor in your eyes, please let me go away and see my brothers.' Therefore he has not come to the king's table."
