'Speech' in the Bible

"For the Lord has finished all his work against Mount Zion and against Jerusalem; he will punish the speech that comes from that willful heart of Assyria's king and the haughty look in his eyes.

"Pay attention! Listen to what I have to say; Pay attention, and hear my speech.

and you will be brought down. You will speak from the ground, and your speech will mumble from the dust. Your voice will come ghostlike from the ground, and your speech will whisper from the dust.

No longer will you see those arrogant people, those people with their obscure speech you cannot comprehend, stammering in a language you cannot understand.
