It is against the laws of humanity, and custom of war, to kill captives, though thou thyself hast taken them with thy own sword and bow, which may seem to give thee some colour of right to destroy them; but much more unworthy will it be in cold blood to kill these, whom not thy arms, but God's miraculous providence, hath put into thy hands. Set bread and water before them, i.e. give them meat and drink, which may refresh and strengthen them for their 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 both mollified towards the Israelites, and afraid to oppose that people who had such an invincible Protector.
