Ezekiel 3:9-11

New Catholic Bible

⁹ I will make your resolve as hard as a diamond. I have made your forehead like the hardest stone, harder than flint. Do not fear them, or be concerned about their appearance, for they are a rebellious house.

¹⁰ He went on: Listen carefully, son of man, to all my words. Receive them into your heart and hear them with your ears. ¹¹ Then go to your countrymen in exile and say to them, “Thus says the Lord,” whether they listen or refuse to listen.
