'My Father' in the Bible

Then David said to God, "Was it not I [who] gave a command to count the people? Now I [am] he who has sinned, and I have certainly done wickedness, but these sheep, what have they done? O Yahweh, my God, please let your hand be against me and against the house of my father, but against your people, [let there be] no plague."

But Yahweh the God of Israel chose me from all of the house of my father to be king over Israel forever, for he chose Judah as leader, and in the house of Judah, the house of my father, and among the sons of my father he took pleasure in me to reign over all Israel.
