Deuteronomy 4:48 WBT

⁴⁶  On the east side of Jordan, in the valley over against Beth-Peor, in the land of Sihon king of the Amorites, who dwelt at Heshbon, whom Moses and the children of Israel smote, after they had come forth from Egypt:

⁴⁷  And they possessed his land, and the land of Og king of Bashan, two kings of the Amorites, who [were] on the side of Jordan, towards the sun-rising;

⁴⁸  From Aroer, which [is] by the bank of the river Arnon, even to mount Sion, which [is] Hermon,

⁴⁹  And all the plain on the side of Jordan eastward, even to the sea of the plain, under the springs of Pisgah.
