Additional books of the Old Testament include the Book of Tobit and the Book of Judith; the First, Second and Third Books of Maccabees. The Catholic Church regards them as canonical of the second order, except the unrecognized Third Book of Maccabees; the Orthodox Church does not consider them canonical, but recognizes them as "spiritually useful"; the Protestant churches equate them with the Apocrypha, that is, they are not sacred; Judaists do not include them in their canon, because in their opinion Yahweh could only speak Hebrew (actually "broadcast" by behind-the-scenes priests hypnotizers), and books are composed in Ancient Greek (koin) and Aramaic. The authors of these books are unknown. Time of supposed writing: IV-I century BC. - The main purpose of the books is to force Jews living in a foreign environment to preserve their faith in Yahweh, as well as to prove to the "chosen people" the invalidity of idolatry and to convince them of the need to observe Jewish norms of behavior and morality necessary to preserve the existence of the Jewish priesthood.
