From Aroer, which is on the edge of the Arnon Valley, and from the city which is in the valley, as far as Gilead, there was no city [whose wall was] too high and too strong for us; the Lord our God handed over everything to us.

“So we took possession of this land at that time. I gave the territory from Aroer, which is by the valley of the Arnon, along with half of the hill country of Gilead and its cities to the Reubenites and to the Gadites.

Moses also gave an inheritance to the tribe of Gad, to the sons of Gad, according to their families.

Sion

(the Sidonians call Hermon Sirion, and the Amorites call it Senir):

It is like the dew of [Mount] Hermon
Coming down on the hills of Zion;
For there the Lord has commanded the blessing: life forevermore.
