'Mouths' in the Bible

He said to me, “Do you see this, son of man? Is it too slight a thing for the house of Judah to commit the repulsive acts which they have committed here, that they have filled the land with violence and repeatedly provoked Me to anger? And behold, they are putting the branch to their nose.

They come to you as people come, and they sit before you as My people, and they hear your words, but they do not practice them; for with their mouth they express loving devotion, but their heart goes after their (unlawful) gain.

‘Thus says the Lord God, “Behold, I am against the shepherds, and I will demand My flock from them and make them stop tending the flock, so that the shepherds cannot feed themselves anymore. I will rescue My flock from their mouth, so that they will not be food for them.”’”
