The Contrast of Elisha's Prayers

Elisha leads the enemy soldiers to Samaria, where he prays that God will open their eyes. He then gives them bread and water so they can eat and drink before going back to their master. The king of Israel is shocked when Elisha doesn't kill his enemies but instead prepares a great feast for them. Paul says in Romans 12: "Never avenged yourselves, but leave it to the Lord"
