Esther 9, 10

When King Xerxes (Ahasuarus) finally saw how he had been deceived into employing Haman’s plot to exterminate the Jews, he openly supported the extinction of Haman and his sons and cohorts. They were all impaled on poles, a Persian form of punishment which could be used as torture and death. The Jews in turn received the king’s blessing to round up all accomplices in Haman’s scheme and likewise execute them.

New Testament Christians are exhorted rather to defer all vengeance to God alone. He makes it clear; Do not take revenge, my dear friends, but leave room for God’s wrath, for it is written: “It is mine to avenge; I will repay,” says the Lord. [Romans 12:19]

For one thing, we can’t see the entire story, only God can. Also, we selfishly see only our suffering in the matter. God can use our suffering for our good, and use the offense to more fully reveal Himself to our oppressor and bring them to repentance and salvation.
