Numbers 21:26

²⁴And Israel smote him with the slaughter of the sword, and they became possessors of his land, from Arnon to Jabbok, as far as the children of Ammon, for Jazer is the borders of the children of Ammon.

²⁵And Israel took all their cities, and Israel dwelt in all the cities of the Amorites, in Heshbon, and in all cities belonging to it.

— Numbers 21:26 —

²⁷Therefore say they who deal in dark speeches, Come to Heshbon, That the city of Sihon may be built and prepared.

²⁸For a fire has gone forth from Heshbon, A flame from the city of Sihon, And has consumed as far as Moab, And devoured the pillars of Arnon.
