'Device' in the Bible

And Esther spake yet again before the king, and fell down at his feet, and besought him with tears to put away the mischief of Haman the Agagite, and his device that he had devised against the Jews.

and saith, 'If to the king it be good, and if I have found grace before him, and the thing hath been right before the king, and I be good in his eyes, let it be written to bring back the letters -- a device of Haman son of Hammedatha the Agagite -- that he wrote to destroy the Jews who are in all provinces of the king,

But when Esther came before the king, he commanded by letters that his wicked device, which he devised against the Jews, should return upon his own head, and that he and his sons should be hanged on the gallows.
