Ezekiel 33:32 says the people listen to Ezekiel like a lovely song. What do they fail to do?

Answer: Put his words into practice

To them Ezekiel was like a singer of love songs with a beautiful voice: "They hear your words but do not put them into practice."

“Indeed, you are to them like a singer of love songs with a beautiful voice, who skillfully plays an instrument. They hear your words but do not put them into practice.”— Ezekiel 33:32 (BSB)
