God uses for good what men intend for evil.

Then his wife Zeresh and all his friends said to him, “Let a gallows be made, fifty cubits high, and in the morning suggest to the king that Mordecai be hanged on it; then go merrily with the king to the banquet.” And the thing pleased Haman; so he had the gallows made.” “That night the king could not sleep. So one was commanded to bring the book of the records of the chronicles; and they were read before the king. And it was found written that Mordecai had told of Bigthana and Teresh, two of the king’s eunuchs, the doorkeepers who had sought to lay hands on King Ahasuerus. Then the king said, “What honor or dignity has been bestowed on Mordecai for this?” And the king’s servants who attended him said, “Nothing has been done for him.”...Now Haman had just entered the outer court of the king’s palace to suggest that the king hang Mordecai on the gallows that he had prepared for him. So Haman came in, and the king asked him, “What shall be done for the man whom the king delights to honor?” Now Haman thought in his heart, “Whom would the king delight to honor more than me?” ... Then the king said to Haman, “Hurry, take the robe and the horse, as you have suggested, and do so for Mordecai the Jew who sits within the king’s gate! Leave nothing undone of all that you have spoken.” So Haman took the robe and the horse, arrayed Mordecai and led him on horseback through the city square, and proclaimed before him, “Thus shall it be done to the man whom the king delights to honor!” When Haman told his wife Zeresh and all his friends everything that had happened to him, his wise men and his wife Zeresh said to him, “If Mordecai, before whom you have begun to fall, is of Jewish descent, you will not prevail against him but will surely fall before him.”  ‭‭Esther 5:12-14,‬ ‭6‬:‭1‬-‭4‬, ‭6‬, ‭10‬-‭11‬, ‭13‬-‭14‬ ‭NKJV‬‬
