Numbers 21:25-27

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

²⁶For Esebon is the city of Seon king of the Amorites; and he before fought against the king of Moab, and they took all his land, from Aroer to Arnon.

²⁷Therefore say they who deal in dark speeches, Come to Esebon, that the city of Seon may be built and prepared.
