Yurāmu is a passive imperfect from rāma, yarūmu, “to seek, intend, or attempt to reach.” Lā negates it, while khibāʾuhā functions as the nominative subject of the passive construction.
The meaning is stronger than merely “the tent is far away.” It represents the place as normally beyond pursuit or approach. The passive construction directs attention to the inaccessibility of the tent rather than identifying the particular people kept out.
Khibāʾ means a tent or temporary dwelling; the suffix -hā connects it with the woman. The phrase thus joins the dwelling, its occupant, and its protected status in a compact description.
