Pensée juive sur Chroniques 1 21:16

After these remarks of mine listen to the following useful instruction given by our Sages, who in truth deserve the title of “wise men”; it makes clear that which appears doubtful, and reveals that which has been hidden, and discloses most of the mysteries of the Law. They said in the Talmud as follows: R. Simeon, son of Lakish, says: “The adversary (satan), evil inclination (yeẓer ha-ra’), and the angel of death, are one and the same being.” Here we find all that has been mentioned by us in such a clear manner that no intelligent person will be in doubt about it. It has thus been shown to you that one and the same thing is designated by these three different terms, and that actions ascribed to these three are in reality the actions of one and the same agent. Again, the ancient doctors of the Talmud said: “The adversary goes about and misleads, then he goes up and accuses, obtains permission, and takes the soul.” You have already been told that when David at the time of the plague was shown the angel “with the sword drawn in his hand stretched out over Jerusalem” (2 Sam. 24:17), it was done for the purpose of conveying a certain idea to him. The same idea was also expressed in the vision concerning the sins of the sons of Joshua, the high priest, by the words, “And the adversary stood on his right hand to accuse him” (Zech. 3:1). The vision then reveals that [the adversary] is far from God, and continues thus: “The Lord will rebuke thee, O adversary, the Lord who hath chosen Jerusalem will rebuke thee” (ibid. ver. 2). Balaam saw prophetically the same vision in his journey, addressing him with the words, “Behold I have come forth to be a hindrance to thee” (Num. 22:32).
