Ezekiel 3:6-8

Revised Standard Version

⁶ not to many peoples of foreign speech and a hard language, whose words you cannot understand. Surely, if I sent you to such, they would listen to you. ⁷ But the house of Israel will not listen to you; for they are not willing to listen to me; because all the house of Israel are of a hard forehead and of a stubborn heart. ⁸ Behold, I have made your face hard against their faces, and your forehead hard against their foreheads.
