'King' in the Bible

Distress and anguish make him afraid. They prevail against him, as a king ready to the battle.

He shall be rooted out of his tent where he trusts. He shall be brought to the king of terrors.

I chose out their way, and sat as chief. I lived as a king in the army, as one who comforts the mourners.

Who says to a king, 'Vile!' or to nobles, 'Wicked!'?

He sees everything that is high. He is king over all the sons of pride."
