Shared ground
These verses present a framed choice: Moses places “today” a blessing and a curse before Israel (explicit textual claim). The blessing is tied to listening to Yahweh’s commands given that day, and the curse is tied to refusing to listen and turning away to “other gods…not known” (explicit textual claims). The passage also links this choice to Israel’s imminent entry into the land Yahweh is giving, and it anticipates a public, place-based act involving Mount Gerizim and Mount Ebal (explicit textual claims).
The text assumes covenant life has real outcomes. It does not describe random fate; it describes consequences connected to covenant loyalty in the land (inference anchored to the explicit blessing/curse conditions).
Where interpretation differs
1) What “set the blessing…set the curse” means in practice.
Some read it as a formal spoken ceremony carried out at those mountains (a public announcement or recitation). Others think it includes visible markers or a more enacted rite that “places” the words and their meaning at that location. The passage itself states the requirement and names the locations, but does not explain the mechanics (interpretive pressure point).
2) What “listen” implies.
Some take “listen” as basically “obey” in a full, concrete sense, since the closing line stresses doing “all the statutes and the ordinances” (v.32). Others hear “listen” as starting with reception and allegiance, with obedience as the expected outworking, without implying perfection (difference in inference; the text ties blessing/curse to listening/not listening and repeats doing the statutes).
3) How to understand “other gods…which you have not known.”
Some take “not known” as meaning these gods were not previously part of Israel’s story or covenant identity (new, foreign loyalties). Others think it emphasizes lack of real relationship or true experience with these gods, contrasting them with Yahweh whom Israel does know through covenant history (difference in nuance; the text does not expand the phrase).
Why the disagreement exists
The passage is programmatic and brief: it states conditions and names places, but leaves key details unstated (what the mountain action looks like; what “listen” includes in full; what “not known” highlights). Those gaps encourage readers to fill in meaning from nearby context and from later passages that describe related ceremonies.
What this passage clearly contributes
It sharpens Deuteronomy 11 into a concrete “before you today” decision framed as blessing versus curse (vv.26–28). It anchors covenant loyalty to exclusive allegiance to Yahweh by naming “turning aside” to unfamiliar gods as the core path of the curse (v.28). It also connects covenant instruction to geography and public memory: Israel’s entry into the land is to include a communal, location-specific setting-forth of blessing and curse at Gerizim and Ebal (vv.29–30). Finally, it re-emphasizes that these are not abstract ideas but “statutes and ordinances” set before the people “today” (v.32; cf. Deuteronomy 11:26).
