On this occasion, laws regarding the Sabbatical year are placed within the Holiness Code (Leviticus 17:1–26:46). This serves as a link with Leviticus 23:1–3 and connects it to the weekly Sabbath. The importance of the Sabbatical year is reinforced by the repetition of the term Sabbath.
The word occurs seven times in the first seven verses.
2 Parle aux enfants d'Israël, et tu leur diras: Quand vous serez entrés dans le pays que je vous donne, la terre se reposera: ce sera un sabbat en l'honneur de l'Eternel.
