Wouldest thou smite ... - It is doubtful whether this sentence is really interrogative. Others translate - "Smite those whom thou hast taken captive with thy sword," etc. A contrast is intended between ordinary captives - those made with the sword and bow - and these particular prisoners who have been given into the king's hand by God. The former, Jehoram is told, he may slay, if he pleases Deuteronomy 20:13, the latter, he is informed, he must not slay (compare the marginal reference).

Whom thou hast taken captive - Those who in open battle either lay down their arms, or are surrounded, and have their retreat cut off, are entitled to their lives, much more those who are thus providentially put into thy hand, without having been in actual hostility against thee. Give them meat and drink, and send them home to their master, and let them thus know that thou fearest him not, and art incapable of doing an ungenerous or unmanly action.

And he answered, thou shalt not smite them,.... For they were not his, but the prophet's captives, or rather the Lord's:

wouldest thou smite those whom thou hast taken captive with thy sword and with thy bow? when soldiers are made prisoners of war, it is contrary to humanity, to the laws of nature and nations, to kill them in cold blood, and much more those who were taken not by his sword and bow, but by the power and providence of God:

set bread and water before them, that they may eat and drink, and go to their master; the king of Syria, and report the miracles wrought, and the good usage they met with, when in the hand of an enemy, fed and let go; which would be more to the glory of the God of Israel, and more agreeable to the character of a king of Israel, reckoned merciful, and more serviceable to the civil good of the land of Israel, as well as more to the honour of the prophet and true religion, see Romans 12:20.

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.

6:22 Wouldest thou smite - It is against the laws of humanity, to kill captives, though thou thyself hast taken them with thy own sword and bow; which might seem to give thee some colour to destroy them; but much more unworthy will it be in cold blood to kill these, whom not thy arms, but God's providence hath put into thy hands. Set bread - Give them meat and drink, which may refresh and strengthen them for their journey. This was an action of singular piety and charity, in doing good to their enemies, which was much to the honour of the true religion; and of no less prudence, that hereby the hearts of the Syrians might be mollified towards the Israelites.

6:13-23 What Elisha said to his servant is spoken to all the faithful servants of God, when without are fightings, and within are fears. Fear not, with that fear which has torment and amazement; for they that are with us, to protect us, are more than they that are against us, to destroy us. The eyes of his body were open, and with them he saw the danger. Lord, open the eyes of our faith, that with them we may see thy protecting hand. The clearer sight we have of the sovereignty and power of Heaven, the less we shall fear the troubles of earth. Satan, the god of this world, blinds men's eyes, and so deludes them unto their own ruin; but when God enlightens their eyes, they see themselves in the midst of their enemies, captives to Satan, and in danger of hell, though, before, they thought their condition good. When Elisha had the Syrians at his mercy, he made it appear that he was influenced by Divine goodness as well as Divine power. Let us not be overcome of evil, but overcome evil with good. The Syrians saw it was to no purpose to try to assault so great and so good a man.
