Angel of Death
The Rabbis found the Angel of Death mentioned in Psalm 89:48, where the Targum translates: "There is no man who lives and, seeing the Angel of Death, can deliver his soul from his hand." Eccl. 8:4 is thus explained in Midrash Rabbah to the passage: "One may not escape the Angel of Death, nor say to him, 'Wait until I put my affairs in order,' or 'There is my son, my slave: take him in my stead.'" Where the Angel of Death appears, there is no remedy, but his name (Talmud, Ned. 49a; Hul. 7b). If one who has sinned has confessed his fault, the Angel of Death may not touch him (Midrash Tanhuma, ed. Buber, 139). God protects from the Angel of Death (Midrash Genesis Rabbah lxviii.).
