Ezekiel 3:7-9

but the people of Israel will refuse to listen to you because they refuse to listen to me. The whole family of Israel has a hard heart and is stubbornly defiant. But now, I will make you as stubborn and defiant as they are! I will make your resolve as hard as the hardest stone, even harder than flint. So do not fear them or be afraid because of their angry stares, for they are a tribe of rebels.”
