That thou mightset still the enemy and the avenger. It scarcely seems as if any single individual—either Absalom, or Ahithophel, or even Satan (Kay)—is intended. Rather the words are used generally of all those who are enemies of God, and desirous of revenging themselves upon him.
The existence of such persons is well shown by Hengstenberg.
