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).
