Esther 5:13-14

Yet all this availeth me nothing, so long as I see Mordecai the Jew sitting at the king’s gate. 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.
