'River' in the Bible

From the wilderness [of Arabia in the south] and this Lebanon [in the north], even as far as the great river, the river Euphrates [in the east], all the land of the Hittites (Canaan), and as far as the Great [Mediterranean] Sea toward the west shall be your territory.

Now these are the kings of the land whom the sons of Israel defeated, and whose land they possessed beyond the Jordan toward the east, from the valley of the [river] Arnon to Mount Hermon, and all the Arabah [plain] to the east:

Sihon king of the Amorites, who lived in Heshbon, and ruled from Aroer, which is on the edge of the valley of the [river] Arnon, both the middle of the valley and half of Gilead, and as far as the brook Jabbok, [which is] the border of the sons of Ammon;

from the Shihor [waterway] which is east of Egypt [at the southern end of Canaan], northward to the border of Ekron (all of it regarded as Canaanite); the five rulers of the Philistines: the Gazite, Ashdodite, the Ashkelonite, the Gittite, the Ekronite; and the Avvite

from Aroer on the edge of the valley of the [river] Arnon, and the city in the middle of the valley, and all the plain of Medeba, as far as Dibon;

Their territory was from Aroer, which is on the edge of the valley of the [river] Arnon, and the city which is in the middle of the valley and all the plain by Medeba;

It went down from Janoah to Ataroth and to Naarah, touched Jericho and ended at the Jordan.

Joshua said to all the people, “This is what the Lord, the God of Israel, says, ‘Your fathers, including Terah, the father of Abraham and the father of Nahor, lived beyond the [Euphrates] River in ancient times; and they served other gods.

Then I took your father Abraham from beyond the [Euphrates] River and led him through all the land of Canaan, and multiplied his descendants, and I gave him Isaac.

“Now, therefore, fear the Lord and serve Him in sincerity and in truth; remove the gods which your fathers served on the other side of the [Euphrates] River and in Egypt, and serve the Lord.

If it is unacceptable in your sight to serve the Lord, choose for yourselves this day whom you will serve: whether the gods which your fathers served that were on the other side of the River, or the gods of the Amorites in whose land you live; but as for me and my house, we will serve the Lord.”
