The author invites us to discover first of all the feasts of the Lord described in three essential texts of the Bible (Leviticus 23 - Numbers 28 - Deuteronomy 16).
 These feasts are in order: Shabbat, Pessa'h (Passover) Shavuoth (Pentecost), the feast of Shofars, Kipur and Sukkot (feast of tabernacles).

 To these festivals is added Purim, in remembrance of the deliverance brought about by God and told in the book of Esther; another feast that is not mentioned in the Old Testament “Hanukkah” (feast of lights) mentioned in the Gospel of John; finally the 9th of the month of Av which recalls the destruction of the temple and Tou Bi Shevat "the new year of the trees" that Jean-Marc Thobois develops with passion to make us discover the hidden meaning of these divine meetings.
