Shared ground
Deuteronomy 3:8–11 functions as a factual recap inside Moses’ retelling of Israel’s recent past. It highlights what was taken, from whom, and where the borders ran: land captured from two Amorite kings “beyond the Jordan,” stretching from the Arnon valley up to Mount Hermon. It also lists major subregions included in that capture—cities of the plain, Gilead, and Bashan—and names Salecah and Edrei as key cities tied to Og’s former kingdom.
The text also treats geography and memory as important. Mount Hermon is said to have multiple local names (Sirion/Senir), implying a landscape shared by different peoples and languages. Og is singled out as the lone survivor of the “remnant of the Rephaim,” and a large iron bedstead associated with him is pointed to as a known object located in Rabbah.
Where interpretation differs
Two issues receive different readings.
First, “beyond the Jordan” can be taken as a fixed expression for the Transjordan area, or as a phrase whose meaning depends on the narrator’s standpoint (east vs. west of the river). The passage itself does not stop to explain the standpoint; it simply uses the phrase while summarizing the conquest.
Second, the bedstead note about Og can be read as (a) a straightforward report of a preserved artifact used as a concrete reminder, or (b) a reference to a well-known local tradition (“isn’t it in Rabbah…?”) that Moses cites because it was commonly talked about, without settling every historical detail in the retelling.
Why the disagreement exists
The passage compresses events into a summary and includes parenthetical asides (the alternate names for Hermon; the note about Og and the bedstead). Those asides sound like “extra information” given for clarity or emphasis, but they do not specify how the audience is expected to evaluate details like viewpoint (“beyond the Jordan”) or the precise nature of the bedstead report.
What this passage clearly contributes
It reinforces that Israel’s possession east of the Jordan is presented as real territory with defined borders and named places (Arnon, Hermon, Gilead, Bashan, Salecah, Edrei). It portrays the victory as involving recognizable political powers (“two Amorite kings”) and a memorable figure (Og), whose association with the Rephaim and an oversized bedstead underscores how formidable the defeated regime was said to be. The passage also shows the narrator’s interest in linking Israel’s story to a broader, multi-people map (Sidonians/Amorites using different names for the same mountain).
