Ezekiel 33:30-33 New Revised Standard Version (NRSV)
30 As for you, mortal, your people who talk together about you by the walls, and at the doors of the houses, say to one another, each to a neighbor, “Come and hear what the word is that comes from the Lord.” 31 They come to you as people come, and they sit before you as my people, and they hear your words, but they will not obey them. For flattery is on their lips, but their heart is set on their gain. 32 To them you are like a singer of love songs,[a] one who has a beautiful voice and plays well on an instrument; they hear what you say, but they will not do it. 33 When this comes—and come it will!—then they shall know that a prophet has been among them.
