Ezekiel 3:26-27

And I will make your tongue stick to the roof of your mouth so that you will be speechless and unable to rebuke them, for they are rebels. But when I give you a message, I will loosen your tongue and let you speak. Then you will say to them, ‘This is what the Sovereign LORD says!’ Those who choose to listen will listen, but those who refuse will refuse, for they are rebels.
