Esther 7:9-10
“Then Harbona, one of the eunuchs who were before the king, said, "Behold, the gallows fifty cubits high, which Haman has made for Mordecai, who spoke good for the king, is standing at Haman's house." The king said, "Hang him on it!" So they hanged Haman on the gallows that he had prepared for Mordecai. Then the king's wrath was pacified.”
This passage comes from the Persian court during the reign of King Ahasuerus. Haman, a high-ranking official, hated Mordecai, a Jewish man, and plotted to destroy him and all his people. Haman had even built towering gallows for Mordecai, unaware that Queen Esther, the king's wife, was Mordecai's cousin and also Jewish.
What systems or personal habits might we unknowingly be building that could ultimately ensnare us?
