Israel's obedience was to be more than skin deep. It was to be a matter of the mind and will. Israel was not to forget their experience of God; they were to be diligent to preserve their memory of him. In addition, they had a duty to teach their children and grandchildren about it.
9 Seulement, prends garde à toi et veille attentivement sur ton âme, tous les jours de ta vie, de peur que tu n'oublies les choses que tes yeux ont vues, et qu'elles ne sortent de ton cœur; enseigne-les à tes enfants et aux enfants de tes enfants.
