'Impious' in the Bible

"Such language is impious," said some of the Scribes among themselves.

This is why I tell you that men may find forgiveness for every other sin and impious word, but that for impious speaking against the Holy Spirit they shall find no forgiveness.

Then the High Priest tore his robes and exclaimed, "Impious language! What further need have we of witnesses! See, you have now heard the impiety.

You all heard his impious words. What is your judgement?" Then with one voice they condemned Him as deserving of death.
