'Father's' in the Bible

Let thine ear now be attentive, and thine eyes open, to hear the prayer of thy servant, which I pray before thee at this time, day and night, for the children of Israel thy servants, confessing the sins of the children of Israel, which we have sinned against thee: both I and my father's house have sinned.

And these are they that went up from Tel-melah, Tel-harsha, Cherub-Addon and Immer; but they could not shew their father's house, nor their seed, whether they were of Israel.
