The historical setting for Ezekiel's word of the LORD is the unwillingness of the people of God, the family of Israel, to be righteous in their ways, to love one another & their neighbors in their actions, every day. Israel has been invaded by Babylon.
30“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 forth from the LORD.’
31And 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 their lips they show much love, but their heart is set on their gain.
32And lo, you are to them like one who sings love songs with a beautiful voice and plays well on an instrument, for they hear what you say, but they will not do it.
33When this comes—and come it will!—then they will know that a prophet has been among them.”
