'Fatal' in the Bible

that {you have made a fatal mistake}, for you sent me to Yahweh your God, {saying}, 'Pray for us to Yahweh our God, and all that Yahweh our God says, so tell us and we will do [it].'

There is no healing for your wound; your injury is fatal. All who hear the report of you will clap [their] hands [for joy] concerning you, {For who has not suffered at the hands of your endless cruelty}?

And one of its heads [appeared] as though slaughtered to death, and its {fatal wound} had been healed. And the whole earth was astonished [and followed] after the beast.

And he exercises all the authority of the first beast on behalf of him, and he causes the earth and those who live in it to worship the first beast {whose fatal wound had been healed}.
