Ezekiel 3:5-9

VIN(i) 5 For you are not sent to a people of a strange speech and of a hard language, but to the house of Israel; 6 and not to many nations of obscure speech and a difficult language whose words you do not understand, for if I had sent you to them they would have listened to you. 7 But the house of Israel is not willing to listen to you, for they are not willing to listen to Me, for all the house of Israel are strong of forehead and hard of heart. 8 "Yet, I will make you as stubborn and as hardheaded as they are. 9 I have made your forehead as a diamond, harder than flint. Don’t be afraid of them, neither be dismayed at their looks, though they are a rebellious house.”
