There was no city that was inaccessible to us, from Aroer on the rim of the Arnon Valley, along with the city in the valley, even as far as Gilead. The Lord our God gave everything to us.

“At that time we took possession of this land. I gave to the Reubenites and Gadites the area extending from Aroer by the Arnon Valley, and half the hill country of Gilead along with its cities.

To the tribe of the Gadites by their clans, Moses gave

Sion

which the Sidonians call Sirion, but the Amorites call Senir,

It is like the dew of Hermon
falling on the mountains of Zion.
For there the Lord has appointed the blessing—
life forevermore.
