A figure known as ha-satan ("the satan") first appears in the Hebrew Bible as a heavenly prosecutor, subordinate to Yahweh (God), who prosecutes the nation of Judah in the heavenly court and tests the loyalty of Yahweh's followers. During the intertestamental period, possibly due to influence from the Zoroastrian figure of Angra Mainyu, the satan developed into a malevolent entity with abhorrent qualities in dualistic opposition to God. In the apocryphal Book of Jubilees, Yahweh grants the satan (referred to as Mastema) authority over a group of fallen angels, or their offspring, to tempt humans to sin and punish them.
