'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}?
