5 The righteousness of the perfect shall direct his way: BUT THE WICKED SHALL FALL BY HIS OWN WICKEDNESS.


Proverbs 11 King James Version (KJV)




From Gill's Exposition of the Entire Bible:



AS HAMAN DID IN THE ROOM OF MORDECAI, and WAS HANGED upon the gallows THE OTHER WAS DELIVERED FROM, and HE HAD PREPARED FOR HIM, Esther 7:9-10;


9 Then Harbona, one of the eunuchs attending the king, said, “A pole reaching to a height of fifty cubitsb stands by Haman’s house. He had it set up for Mordecai, who spoke up to help the king.”

The king said, “Impale him on it!” 10 So they impaled Haman on the pole HE HAD SET UP FOR MORDECAI. Then the king’s fury subsided.

The same case for Judah, THE WICKED SHALL FALL BY HIS OWN WICKEDNESS.
