'Speech' in the Bible

For Jerusalem has stumbled and Judah has fallen,Because their words and their actions are against the Lord,To rebel against His glorious presence and defiantly provoke Him.

Then you [Jerusalem] will be brought low,You will speak from the earth,And from the dust where you lie face downYour muffled words will come.Your voice will also be like that of a spirit from the earth [like one produced by a medium],And your speech will whisper and squeak from the dust.

You will no longer see the fierce and insolent people,A people of unintelligible speech which no one comprehends,Of a strange and stammering tongue which no one understands.

As I create the praise of his lips,Peace, peace, to him who is far away [both Jew and Gentile] and to him who is near!”Says the Lord;“And I will heal him [making his lips blossom anew with thankful praise].”
