The verse centers on "gave", "isaac", "jacob", "esau", "mount", and "seir". It is saying that the verse draws attention to "gave" and "isaac", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 3's "And I took your father Abraham from..." into verse 5's "I sent Moses also and Aaron and...", so "gave" and "isaac" belong inside that flow. In Joshua context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "gave" and "isaac" with trust shaped by these words, not by a vague optimism outside the passage.
