Numbers 21:26 DBY

²⁴  And Israel smote him with the edge of the sword, and took possession of his land from the Arnon to the Jabbok, even unto the children of Ammon; for the border of the children of Ammon was strong.

²⁵  And Israel took all these cities, and Israel dwelt in all the cities of the Amorites, at Heshbon, and in all its dependent villages.

²⁶  For Heshbon was the city of Sihon the king of the Amorites; and he had fought against the former king of Moab, and had taken all his land out of his hand, even unto the Arnon.

²⁷  Therefore the poets say, Come to Heshbon; let the city of Sihon be built and established.

²⁸  For there went forth fire from Heshbon, a flame from the city of Sihon; It consumed Ar of Moab, the lords of the high places of the Arnon.
