Book of Jubilees in the context of "Jewish apocrypha"

A pseudepigraph (also anglicized as "pseudepigraphon") is a falsely attributed work, a text whose claimed author is not the true author, or a work whose real author attributed it to a figure of the past. The name of the author to whom the work is falsely attributed is often prefixed with the particle "pseudo-", such as "pseudo-Aristotle" or "pseudo-Dionysius." These terms refer to the anonymous authors of works falsely attributed to Aristotle and Dionysius the Areopagite, respectively.

In biblical studies, the term pseudepigrapha can refer to an assorted collection of Jewish religious works thought to be written c. 300 BCE to 300 CE. They are distinguished by Protestants from the deuterocanonical books (Catholic and Orthodox) or Apocrypha (Protestant), the books that appear in extant copies of the Septuagint in the fourth century or later and the Vulgate, but not in the Hebrew Bible or in Protestant Bibles. In Catholic usage, the Old Testament books accepted by the Catholic Church are referred to as the deuterocanonical books, and Catholic writers commonly reserve the word apocrypha for spurious or noncanonical writings rather than for the deuterocanon. In addition, two books considered canonical in the Orthodox Tewahedo churches, the Book of Enoch and Book of Jubilees, are noncanonical in Catholic and Eastern Orthodox canons and are classified by most scholars among the Old Testament pseudepigrapha.

Predestination, in theology, is the doctrine that all events have been willed by God, usually with reference to the eventual fate of the individual soul. Explanations of predestination often seek to address the paradox of free will, whereby God's omniscience seems incompatible with human free will. In this usage, predestination can be regarded as a form of religious determinism; and usually predeterminism, also known as theological determinism.

Predestination has been a topic of debate throughout Jewish and Christian history. In pre-Christian texts like the Book of Enoch and the Book of Jubilees, some writings suggest a mix of determinism and free will, while authors like Ben Sira affirm human choice. Scholars debate New Testament passages such as Romans 8–11, with interpretations ranging from predestination being corporate or service-based, to God choosing some individuals for salvation while leaving others to reprobation. Jewish groups like the Essenes may have believed in predestination, but there were complex differences among sects.

Satan, also known as the Devil, is an entity in Abrahamic religions who entices humans into sin or falsehood. In Judaism, Satan is seen as an agent subservient to God, typically regarded as a metaphor for the yetzer hara, or 'evil inclination'. In Christianity and Islam, he is usually seen as a fallen angel or jinn who has rebelled against God, who nevertheless allows him temporary power over the fallen world and a host of demons. In the Baháʼí Faith, Satan is not regarded as an independent evil power, but signifies the lower nature of humans.

A figure known as ha-satan ("the satan") first appears in the Hebrew Bible as a heavenly prosecutor, subordinate to Yahweh (God); he 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.

Arioch (Hebrew: אַרְיוֹךְ, romanized: ’Aryōḵ) appears in Genesis 14 as the name of the King of Ellasar (Hebrew: אֶלָּסָר) who participated in the Battle of Siddim. Led by Chedorlaomer, the four kings Amraphel, Arioch, Chedorlaomer, and Tidal engaged in a punitive expedition against five kings of Canaan who rebelled against Chedorlaomer, Bera of Sodom, Birsha of Gomorrah, Shinab of Admah, Shemeber of Zeboim, and Zoar of Bela. The same story is also mentioned in the Book of Jubilees, where Arioch is called "king of Sellasar". According to Genesis Apocryphon (col. 21), Arioch was king of Cappadocia.

Mastema (Hebrew: מַשְׂטֵמָה Masṭēmā; Ge'ez: መሰቴማ Mesetēma), Mastemat, or Mansemat, is an antagonistic angel in the Book of Jubilees. He first appears in the literature of the Second Temple Period as a personification of the Hebrew word mastemah (מַשְׂטֵמָה), meaning "hatred", "hostility", "enmity", or "persecution".

In the Book of Jubilees, Mastema requests hosts of demons, the spirits of the Nephilim, from God to tempt and corrupt humanity. He appears to various prophets and puts them to the test. Throughout the work, Mastema substitutes evil actions attributed to Yahweh in the Torah and removes malice from the Godhead of the Hebrew tradition. Nevertheless, Mastema remains subordinate to the Godhead.
