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. The entire house of Israel certainly is 2stubborn and obstinate.

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

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