Isaiah 29:13

Ezekiel 33:31-33 NIV
My people come to you, as they usually do, and sit before you to hear your words, but they do not put them into practice. Their mouths speak of love, but their hearts are greedy for unjust gain. Indeed, to them you are nothing more than one who sings love songs with a beautiful voice and plays an instrument well, for they hear your words but do not put them into practice. “When all this comes true—and it surely will—then they will know that a prophet has been among them. ”

Jeremiah 12:2 NIV
You have planted them, and they have taken root; they grow and bear fruit. You are always on their lips but far from their hearts.
