Ezekiel 3:7-9

7yet the house of Israel will not be willing to listen to you, since they are 1not willing to listen to Me. Surely the whole house of Israel is 2stubborn and obstinate.

8Behold, I have made your face as hard as their faces and your forehead as hard as their foreheads.

9Like 3emery harder than flint I have made your forehead. Do not be afraid of them or be dismayed before them, though they are a rebellious house.”
