Ezekiel 3:7-9

3:7 But the house of Israel is unwilling to listen to you, because they are not willing to listen to me, for the whole house of Israel is hard-headed and hard-hearted.

3:8 “I have made your face adamant to match their faces, and your forehead hard to match their foreheads. 3:9 I have made your forehead harder than flint – like diamond! Do not fear them or be terrified of the looks they give you, for they are a rebellious house.”
