'Gallows' in the Bible

Then said Zeresh his wife and all his friends unto him, Let a gallows be made fifty cubits high, and in the morning speak thou unto the king that Mordecai may be hanged thereon: then go thou in merrily with the king unto 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 was come into the outward court of the king's house, to speak unto the king to hang Mordecai on the gallows that he had prepared for him.

Then said Harbonah, one of the chamberlains that were before the king, Behold also, the gallows fifty cubits high, which Haman hath made for Mordecai, who spake good for the king, standeth in the house of Haman. And the king said, Hang him thereon.

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

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

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

but when the matter 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 that he and his sons should be hanged on the gallows.
