Ezekiel 3:9, 26, 27

I will make your forehead like the hardest stone, harder than flint. Do not be afraid of them or terrified by them, though they are a rebellious people.”

I will make your tongue stick to the roof of your mouth so that you will be silent and unable to rebuke them, for they are a rebellious people.

But when I speak to you, I will open your mouth and you shall say to them, ‘This is what the Sovereign LORD says.’ Whoever will listen let them listen, and whoever will refuse let them refuse; for they are a rebellious people.
