The weekly Sabbath was first established by God at the conclusion of creation (Genesis 2:1–3). It is therefore foundational to the structure of the world. Additionally, the principle of one in seven affects the entire festival structure within this chapter. For example, seven festivals are mentioned, most of which occur in the seventh month of the year.
3 On travaillera six jours; mais le septième jour est le sabbat, le jour du repos: il y aura une sainte convocation. Vous ne ferez aucun ouvrage: c'est le sabbat de l'Eternel, dans toutes vos demeures.
