Torah Temimah (Shabbos 116a and related): the section “ויהי בנסוע הארון” is marked with inverted nuns — it is a separate book, or a displacement, according to the views in the sugya.
English: “And it was when the Aron set out” — marked with inverted nuns; a book on its own, or a section that was uprooted (according to the views).
Special status of the unit — the graphic signs signal that these verses stand apart.
The Torah itself marks this prayer as a distinct unit within the larger narrative.
