Passage
Hesebon was the city of Sehon the king of the Amorrhites, who fought against the king of Moab: and took all the land, that had been of his dominion, as far as the Arnon.
Hesebon was the city of Sehon the king of the Amorrhites, who fought against the king of Moab: and took all the land, that had been of his dominion, as far as the Arnon.
Numbers 21:24 And he was slain by them with the edge of the sword, and they possessed his land from the Arnon unto the Jeboc, and to the confines of the children of Ammon: for the borders of the Ammonites, were kept with a strong garrison.
Numbers 21:25 So Israel took all his cities, and dwelt in the cities of the Amorrhite, to wit, in Hesebon, and in the villages thereof.
Numbers 21:26 Hesebon was the city of Sehon the king of the Amorrhites, who fought against the king of Moab: and took all the land, that had been of his dominion, as far as the Arnon.
Numbers 21:27 Therefore it is said in the proverb: Come into Hesebon, let the city of Sehon be built and set up:
Numbers 21:28 A fire is gone out of Hesebon, a flame from the city of Sehon, and hath consumed Ar of the Moabites, and the inhabitants of the high places of the Arnon.
The verse centers on "hesebon", "city", "sehon", "king", "amorrhites", "fought", and "against". It is saying that the verse draws attention to "hesebon" and "city", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 25's "So Israel took all his cities and..." into verse 27's "Therefore it is said in the proverb...", so "hesebon" 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 "hesebon" and "city" with trust shaped by these words, not by a vague optimism outside the passage.
