'Blamelessness' in the Bible

So Yahweh {asked} Satan, "Have you {considered} my servant Job? Indeed, there is no one like him on the earth--a blameless man and upright and God-fearing and turning away from evil. And still he persists in his blamelessness {even though} you incited me against him to destroy him for nothing."

Then his wife said to him, "Are you still persisting in your blamelessness? {Curse} God and die."

Far be it from me that {I would say that you are right}; until I pass away, I will not put away from me my blamelessness.

let him weigh me in [the] balance of justice, and let God know my blamelessness.
