'Device' in the Bible

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

but when this became known to the king, he commanded by letters that his wicked device, 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.
