The setting is Israel camped east of the Jordan, near Moab, after military victories over Transjordanian kingdoms. In that world, stable settlement depended on clear tribal allotments, recognized borders, and remembered place names. The passage assumes a map of local rivers, valleys, and regions (Arnon, Jabbok, Arabah, Bashan, Gilead), and it also assumes neighboring peoples at the edges (Geshurites, Maacathites, Ammon). Moses’ report functions like a public record: it ties land claims to conquest, to named groups within Israel, and to observable geographic markers.
