'Plan' in the Bible

Then Esther spoke to the king again and fell at his feet. She wept and pleaded with him for mercy to overturn the evil plan devised by Haman the Agagite and his plot against the Jewish people.

But when the matter was brought before the king, he commanded by letter that the evil plan Haman had devised against the Jews return on his own head and that he should be hanged with his sons on the gallows.
