'Region' in the Bible

I am depressed, so I will pray to you while I am trapped here in the region of the upper Jordan, from Hermon, from Mount Mizar.

He did amazing things in the sight of their ancestors, in the land of Egypt, in the region of Zoan.

when he performed his awesome deeds in Egypt, and his acts of judgment in the region of Zoan.

Are your amazing deeds experienced in the dark region, or your deliverance in the land of oblivion?
