'Gallows' in the Bible

Then said Zeresh his wife and all his friends to him, Let a gallows be made of fifty cubits high, and in the morning speak to the king that Mordecai may be hanged on it: then go in merrily with the king to the banquet. And the thing pleased Haman; and he caused the gallows to be made.

And the king said, Who is in the court? Now Haman had come into the outward court of the king's house, to speak to the king to hang Mordecai on the gallows that he had prepared for him.

And Harbonah, one of the chamberlains, said before the king, Behold, also, the gallows fifty cubits high, that Haman made for Mordecai, who spoke good for the king, stands in the house of Haman. And the king said, Hang him on it!

So they hanged Haman on the gallows that he had prepared for Mordecai. And the king's wrath was appeased.

And king Ahasuerus said to queen Esther and to Mordecai the Jew, Behold, I have given Esther the house of Haman, and him they have hanged upon the gallows, because he stretched forth his hand against the Jews.

And Esther said, If it please the king, let it be granted to the Jews that are in Shushan to do to-morrow also according to this day's decree, and let Haman's ten sons be hanged upon the gallows.

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