The verse centers on "heshbon", "city", "sihon", "king", "amorites", "fought", "against", and "former". It is saying that the verse draws attention to "heshbon" and "city", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 25's "And Israel took all these cities and..." into verse 27's "Therefore those who use proverbs say Come...", so "heshbon" and "city" belong inside that flow. In Numbers context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "heshbon" and "city" with trust shaped by these words, not by a vague optimism outside the passage.
