Ezekiel 3:6-8

Amplified Bible

⁶ not to many peoples of unintelligible speech or difficult language, whose words you cannot understand. But I have sent you to them who should listen to you and pay attention to My message; ⁷ yet the house of Israel will not be willing to listen to you and obey you, since they are not willing to listen to Me and obey Me, for the entire house of Israel is stubborn and obstinate. ⁸ Behold, I have made your face as hard as their faces and your forehead as hard as their foreheads.
