'King' in the Bible

Trouble and anguish shall make him afraid; they shall prevail against him, as a king ready to the battle.

His confidence shall be rooted out of his tabernacle, and it shall bring him to the king of terrors.

I chose out their way, and sat chief, and dwelt as a king in the army, as one that comforteth the mourners.

Is it fit to say to a king, Thou art wicked? and to princes, Ye are ungodly?

He beholdeth all high things: he is a king over all the children of pride.
