Shared ground
Deuteronomy opens by framing what follows as public instruction: “the words” Moses spoke to all Israel (explicit textual claim). The speech is anchored to a real time and place: beyond the Jordan, in the wilderness/Arabah region, and later specified as the land of Moab (explicit). The careful scene-setting signals that the coming material is meant to be heard as Moses’ final, covenant-shaped address at the end of the wilderness period.
The introduction also ties Moses’ teaching to two sources of authority in the story: (1) Moses is the speaker; (2) what he speaks is “according to all that Yahweh had given him” to command Israel (explicit). That makes the speech more than personal advice; it presents itself as God-directed instruction delivered through Moses.
Finally, the timing note (“fortieth year… eleventh month… first day”) and the mention of victories over Sihon and Og locate the speech after major turning points (explicit). The narrative assumes Israel is now stabilized east of the Jordan and preparing for the next stage.
Where interpretation differs
1) What exactly “beyond the Jordan” means. Some read it as a fixed expression meaning “east of the Jordan” from the viewpoint of the land Israel will enter; others think it reflects the viewpoint of someone writing from the west side later, using the Jordan as the reference line. The text itself gives “land of Moab” as a concrete locator, but the phrase can still be understood differently.
2) Why the “eleven-day journey” detail is included. Many take it as a hint of irony or tragedy: a trip that should have been short became decades long. Others read it more neutrally as a geographic marker that helps the audience picture the route from Horeb to Kadesh-barnea.
3) What “began… to declare this law” covers. Some think it means Moses starts explaining a broad body of instruction associated with the Torah; others think it points more narrowly to the covenant teaching that Deuteronomy will restate and apply for the next generation.
Why the disagreement exists
The opening uses brief orientation phrases that are naturally “elastic”: geographic language depends on viewpoint, and the narrator does not explain the purpose of the travel-time note. Likewise, “this law” can refer to a wide set of commands or to the specific covenant instruction Moses is about to expound.
What this passage clearly contributes
These verses establish that Deuteronomy is set as Moses’ addressed teaching to the whole community at a specific moment: late in the wilderness period, east of the Jordan in Moab, after key victories. They also present Moses’ speech as aligned with what Yahweh had commanded, and they quietly set up the theme of delayed entry (an eleven-day journey contrasted with the fortieth-year timestamp) without yet retelling the reasons.
