Deuteronomy 31:26, ““Take this Book of the Law and place it beside the ark of the covenant of the LORD your God, so that it may remain there as a witness against you.” The stone tablets were placed inside the ark, but the book that Moses had written was not. The ten commandments are eternal, the book of the law that contains the history, the covenant between mankind and the Creator, the punishment for sin and the instructions for applying the law will end when heaven and earth are remade.
