'King' in the Bible

Distress and pressure terrify him; they overwhelm him, like a king poised for attack.

Torn from the security of his home, he is brought before the king of terrors.

I set an example of the way to live, as a leader would; I lived like a king among his army; like one who comforts mourners."

Can one say to a king, "You're vile!' or to nobles, "You're wicked!'?
