In rabbinic literature
Early rabbinic Jewish statements in the Mishnah and Talmud show that Satan played little or no role in Jewish theology. In the course of time, however, Judaism absorbed the popular concepts of Satan, which doubtless forced their way gradually from the lower classes to the most cultured. The later a rabbinc work can be dated the more frequent is the mention therein of Satan and his hosts.
The Palestinian Talmud, completed about 450 CE, is more reticent in this regard; and this is the more noteworthy since its provenience is the same as that of the New Testament.
In a midrash (Genesis Rabbah) Samael, the lord of the satans, was a mighty prince of angels in heaven (Gen. R. xix.). Satan came into the world with woman, i.e., with Eve (Midrash Yalk., Gen. i. 23); so that he was created and is not eternal. Like all celestial beings, he flies through the air (Genesis Rabbah xix.), and can assumeany form, as of a bird (Talmud, Sanhedrin 107a), a stag (ib. 95a), a woman (Ḳid. 81a), a beggar, or a young man (Tan., Wayera, end); he is said to skip (Talmud Pesachim 112b; Meg. 11b), in allusion to his appearance in the form of a goat.
In some works some rabbis hold that Satan is the incarnation of all evil, and his thoughts are devoted to the destruction of man. In this view, Satan, the impulse to evil and the angel of death are one and the same personality. Satan seizes upon even a single word which may be prejudicial to man; so that "one should not open his mouth unto evil," i.e., "unto Satan" (Talmud Berachot 19a). In times of danger likewise he brings his accusations (Palestinian Talmud, Shabbat 5b). While he has power over all the works of man (Talmud Berachot 46b), he can not prevail at the same time against two individuals of different nationality; so that Samuel, a noted astronomer and teacher of the Law (d. at Nehardea 247), would start on a journey only when a Gentile traveled with him (Shab. 32a).
Satan's knowledge is circumscribed; for when the shofar is blown on New-Year's Day he is "confounded" (R. H. 16b; Yer. Targ. to Num. x. 10). On the Day of Atonement his power vanishes; for the numerical value of the letters of his name (See gematria) is only 364, one day being thus exempt from his influence (Yoma 20a).
If Satan does not attain his purpose, as was the case in his temptation of Job, he feels great sorrow (B. B. 16a); and it was a terrible blow to him, as the representative of moral evil, that the Torah, the incarnation of moral good, should be given to Israel. He endeavored to overthrow it, and finally led the people to make the golden calf (Shab. 89a; Yer. Targ. to Ex. xxxii. 1), while the two tables of the Law were bestowed on Moses of necessity without Satan's knowledge (Sanh. 26b).
One rabbi notes that Satan was an active agent in the fall of man (Midrash Pirke R. El. xiii., beginning), and was the father of Cain (ib. xxi.), while he was also instrumental in the offering of Isaac (Tan., Wayera, 22 [ed. Stettin, p. 39a]), in the release of the animal destined by Esau for his father (Tan., Toledot, 11), in the theophany at Sinai, in the death of Moses (Deut. R. xiii. 9), in David's sin with Bath-sheba (Sanh. 95a), and in the death of Queen Vashti (Meg. 11a). The decree to destroy all the Jews, which Haman obtained, was written on parchment brought by Satan (Esther R. iii. 9). When Alexander the Great reproached the Jewish sages with their rebellion, they made the plea that Satan had been too mighty for them (Tamid 32a).
