'Family' in the Bible

And Saul answered and said, Am not I a Benjamite, of the smallest of the tribes of Israel? and my family the least of all the families of the tribe of Benjamin? wherefore then speakest thou to me after this manner?

And 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.

And David said unto 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 thy father miss me at all, then say, David earnestly asked leave of me that he might run to Beth-lehem his city; for it is the yearly sacrifice there for all the family.

and he said, Let me go, I pray thee; for our family hath a sacrifice in the city; and my brother, he hath commanded me to be there : and now, if I have found favor in thine eyes, let me get away, I pray thee, and see my brethren. Therefore he is not come unto the king's table.
