The sons of half-Manasseh “in the land” east of Jordan. The translation should be: “And the children... dwelt in the land, from Bashan unto Baal-hermon and Senir and mount Hermon. These were many.” Their territory extended from “Bashan,” the domain of Gad, in the south, to the mountains of Hermon, or Antilibanus, in the north.
