2 Kings 6:15-23

15. When the servant of the man of God got up and went out early the next morning, an army with horses and chariots had surrounded the city. "Oh, my lord, what shall we do?" the servant asked.
16. "Don't be afraid," the prophet answered. "Those who are with us are more than those who are with them."
17. And Elisha prayed, "O LORD, open his eyes so he may see." Then the LORD opened the servant's eyes, and he looked and saw the hills full of horses and chariots of fire all around Elisha.
18. As the enemy came down toward him, Elisha prayed to the LORD, "Strike these people with blindness." So he struck them with blindness, as Elisha had asked.
19. Elisha told them, "This is not the road and this is not the city. Follow me, and I will lead you to the man you are looking for." And he led them to Samaria.
20. After they entered the city, Elisha said, "LORD, open the eyes of these men so they can see." Then the LORD opened their eyes and they looked, and there they were, inside Samaria.
21. When the king of Israel saw them, he asked Elisha, "Shall I kill them, my father? Shall I kill them?"
22. "Do not kill them," he answered. "Would you kill men you have captured with your own sword or bow? Set food and water before them so that they may eat and drink and then go back to their master."
23. So he prepared a great feast for them, and after they had finished eating and drinking, he sent them away, and they returned to their master. So the bands from Aram stopped raiding Israel's territory.

Luke 6:27-35

27. "But I tell you who hear me: Love your enemies, do good to those who hate you,
28. bless those who curse you, pray for those who mistreat you.
29. If someone strikes you on one cheek, turn to him the other also. If someone takes your cloak, do not stop him from taking your tunic.
30. Give to everyone who asks you, and if anyone takes what belongs to you, do not demand it back.
31. Do to others as you would have them do to you.
32. "If you love those who love you, what credit is that to you? Even `sinners' love those who love them.
33. And if you do good to those who are good to you, what credit is that to you? Even `sinners' do that.
34. And if you lend to those from whom you expect repayment, what credit is that to you? Even `sinners' lend to `sinners,' expecting to be repaid in full.
35. But love your enemies, do good to them, and lend to them without expecting to get anything back. Then your reward will be great, and you will be sons of the Most High, because he is kind to the ungrateful and wicked.
