Ezekiel 33:30-33 ESV

“As for you, son of man, your people who talk together about you by the walls and at the doors of the houses, say to one another, each to his brother, ‘Come, and hear what the word is that comes from the LORD.’ And they come to you as people come, and they sit before you as my people, and they hear what you say but they will not do it; for with lustful talk in their mouths they act; their heart is set on their gain. And behold, you are to them like one who sings lustful songs with a beautiful voice and plays well on an instrument, for they hear what you say, but they will not do it. When this comes—and come it will!—then they will know that a prophet has been among them.”
