'Mouths' in the Bible

This is what the Lord saysconcerning the prophetswho lead my people astray,who proclaim peacewhen they have food to sink their teeth intobut declare war against the onewho puts nothing in their mouths.

Then the seers will be ashamedand the diviners disappointed.They will all cover their mouthsbecause there will be no answer from God.

For the wealthy of the city are full of violence,and its residents speak lies;the tongues in their mouths are deceitful.

Nations will see and be ashamedof all their power.They will put their hands over their mouths,and their ears will become deaf.
