'Father's' in the Bible

Now the priest of Midian had seven daughters: and they came to get water for their father's flock.

And Amram took Jochebed, his father's sister, as wife; and she gave birth to Aaron and Moses: and the years of Amram's life were a hundred and thirty-seven.

The Lord is my strength and my strong helper, he has become my salvation: he is my God and I will give him praise; my father's God and I will give him glory.
