Learn From Haman's Sin

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!” Afterward Mordecai went back to the kings’ gate. But Haman hurried to his house, mourning and with his head covered. 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 6:11-13
Haman’s wife foretells of her husband’s impending demise. She and the wise men surrounding Haman also declare the divine protection that surrounds the Jews. Biblical curses followed the Amalekites because of their long standing conflict with Israel. The God of Abraham, Isaac and Jacob swore in Exodus 17:16 that He would be at war with every generation of Amalekites. Haman, the Amalekite, plotted the destruction of the Jews, as did his ancestors, therefore his downfall was eminent.
The Lord is the same, yesterday, today and forever. He promises to bless those who bless His chosen and curse those that curse Israel and her people
