Isaiah 37:23

When hast thou reproached? - Not an idol. Not one who has no power to take vengeance, or to defend the city under his protection, but the living God.

Exalted thy voice - That is, by thy messenger. Thou hast spoken in a loud, confident tone; in the language of reproach and threatening.

And lifted up thine eyes on high - To lift up the eyes is an indication of haughtiness and pride. He had evinced arrogance in his manner, and he was yet to learn that it was against the living and true God.
