A time to kill, and a time to heal,.... A time to kill may be meant of a violent death, as a time to die is of a natural one; so the Targum,"a time to kill in war;''or else, by the hand of the civil magistrate, such who deserve death.
Aben Ezra interprets it "to wound", because of the opposite "to heal"; and so there is a time when wounds and diseases are incurable, and baffle all the skill of the physician, being designed unto death; and there is a time when, by the blessing of God on means, they are healed; the wound or sickness not being unto death: so the Targum paraphrases the last clause,"to heal one that lies sick.'
