'Blasphemed' in the Bible

And Isaiah said unto them, Thus shall ye say to your master, Thus saith the LORD, Be not afraid of the words which thou hast heard, with which the servants of the king of Assyria have blasphemed me.

Whom hast thou reproached and blasphemed? and against whom hast thou exalted thy voice, and lifted up thine eyes on high? even against the Holy One of Israel.
