'Realm' in the Bible

So Moses gave to the Gadites, the Reubenites, and to half the tribe of Manasseh son of Joseph the realm of King Sihon of the Amorites, and the realm of King Og of Bashan, the entire land with its cities and the territory surrounding them.

It encompassed all the cities of the plain and the whole realm of King Sihon of the Amorites who ruled in Heshbon. Moses defeated him and the Midianite leaders Evi, Rekem, Zur, Hur, and Reba (they were subjects of Sihon and lived in his territory).

It included the valley of Beth Haram, Beth Nimrah, Succoth, and Zaphon, and the rest of the realm of King Sihon of Heshbon, the area east of the Jordan to the end of the Sea of Kinnereth.

Their territory started at Mahanaim and encompassed all Bashan, the whole realm of King Og of Bashan, including all sixty cities in Havvoth Jair in Bashan.

For no one remembers you in the realm of death, In Sheol who gives you thanks?

And he said to him, "To you I will grant this whole realm -- and the glory that goes along with it, for it has been relinquished to me, and I can give it to anyone I wish.
