Decides that that tag fits the whole of the bible.
Here let me save you some time. This is what is on storeage in the library of religious history, Rome. Have fun.
In Jewish, Christian, and Muslim theology, the supreme spirit of evil (Beelzebub, Lucifer, Iblis), or an evil spirit generally.
The Devil, or Satan, is mentioned only in the more recently written books of the Old Testament, but the later Jewish doctrine is that found in the New Testament. The concept of the Devil passed into the early Christian church from Judaism, and theology until at least the time of St Anselm represented the Atonement as primarily the deliverance, through Jesus's death, of humankind from the bondage of the Devil. Jesus recognized as a reality the kingdom of evil, of which Satan or Beelzebub was the prince. In the Middle Ages, the Devil in popular superstition assumed the attributes of the horned fertility gods of paganism, and was regarded as the god of witches. The belief in a personal devil was strong during the Reformation, and the movement's leader Luther regarded himself as the object of a personal Satanic persecution. With the development of liberal Protestantism in the 19th century came a strong tendency to deny the existence of a positive spirit of evil, and to explain the Devil as merely a personification.
However, the traditional conception was never abandoned by the Roman Catholic Church, and theologians such as C S Lewis have maintained the existence of a power of evil.
In Muslim theology, Iblis is one of the jinn (beings created by Allah from fire), who refused to prostrate himself before Adam, and who tempted Adam and his wife Hawwa (Eve) to disobey Allah, an act that led to their expulsion from Paradise. He continues to try to lead people astray, but at the Last Judgement he and his hosts will be consigned to hell.
From the Jewish encyclopedia on the word devil.
Term used in the Bible with the general connotation of "adversary," being applied (1) to an enemy in war (I Kings v. 18 [A. V. 4]; xi. 14, 23, 25), from which use is developed the concept of a traitor in battle (I Sam. xxix. 4); (2) to an accuser before the judgment-seat (Ps. cix. 6); and (3) to any opponent (II Sam. xix. 23 [A. V. 22]). The word is likewise used to denote an antagonist who puts obstacles in the way, as in Num. xxii. 32, where the angel of God is described as opposing Balaam in the guise of a satan or adversary; so that the concept of Satan as a distinct being was not then known. Such a view is found, however, in the prologue to the Book of Job, where Satan appears, together with other celestial beings or "sons of God," before the Deity, replying to the inquiry of God as to whence he had come, with the words: "From going to and fro in the earth, and from walking up and down in it" (Job i. 7). Both question and answer, as well as the dialogue which follows, characterize Satan as that member of the divine council who watches over human activity, but with the evil purpose of searching out men's sins and appearing as their accuser. He is, therefore, the celestial prosecutor, who sees only iniquity; for he persists in his evil opinion of Job even after the man of Uz has passed successfully through his first trial by surrendering to the will of God, whereupon Satan demands another test through physical suffering (ib. ii. 3-5).
The jewish may not now claim to beleive in the devil, Just as the roman catholic claim to never have performed exorsisms, but it does not change the fact that they did and do have storys that teach of a devil, therfore your statement to them not beleiving in one is wrong, I am sorry but that is life. Oh and further more the religion is based on the old testament of the bible to say they don't beleive in the devil is to say that they don't beleive in the bible.
