And he answered, Thou shalt not smite them: wouldest thou smite those whom thou hast taken captive with thy sword and with thy bow? set bread and water before them, that they may eat and drink, and go to their master.
Context
21 The king of Israel said to Elisha, when he saw them, “My father, shall I strike them? Shall I strike them?”
22 He answered, “You shall not strike them. Would you strike those whom you have taken captive with your sword and with your bow? Set bread and water before them, that they may eat and drink, then go to their master.”
23 He prepared a great feast for them. After they ate and drank, he sent them away and they went to their master. So the bands of Syria stopped raiding the land of Israel.
