The term ha-Satan means literally the-Adversary, and the term is used in a number of contexts that mean adversary in general. The closest thing that we find to the Christian concept is its use as the title (though not the name) assigned to an angel in Yahweh's court.
He was a prosecutor for God against human individuals, with God as the Judge. Ha-Satan could not act without God's permission and did not cause people to sin, though God may have ha-Satan test a person, as in the case of Job. Ha-Satan's primary role was to record and point out the sins people committed and argue against them in the holy court in accordance with God's will. In the (apocryphal) book of Enoch, Satanael/Samyaza is the leader of the Grigori, who again were cast out of heaven for sleeping with human women and producing a race of giants.
Shaiten did not become Satan until much later where Jewish sects / tribes particularly the Essenes who began referring to anyone not an Essene as the Shaiten. Still further on the Roman Christian church decided it was time to personify Shaiten into Satan and have Him become the scapegoat for all evil in the Christian world.
Of course this is all within the confines of the Abrahamic religions, as mentioned before, Luciferians, Satanists and LHP'ers do not acknowledge these make believe entities but rather the archetypal roles and affect they have on our Self.
