'Father's' in the Bible

Jehoram took control of his father's kingdom and became powerful. Then he killed all his brothers, as well as some of the officials of Israel.

but have instead followed in the footsteps of the kings of Israel. You encouraged the people of Judah and the residents of Jerusalem to be unfaithful to the Lord, just as the family of Ahab does in Israel. You also killed your brothers, members of your father's family, who were better than you.

He did evil in the sight of the Lord like Ahab's dynasty because, after his father's death, they gave him advice that led to his destruction.

The people of the land took Jehoahaz son of Josiah and made him king in his father's place in Jerusalem.
