'Scheme' in the Bible

Then Esther spoke again to the king, fell at his feet, wept and implored him to avert the evil scheme of Haman the Agagite and his plot which he had devised against the Jews.

But when it came to the king’s attention, he commanded by letter that his wicked scheme which he had devised against the Jews, should return on his own head and that he and his sons should be hanged on the gallows.
