River

Boyd’s Bible Dictionary:

(banked). In Hebrew sense, a large flowing stream, rivulet, ravine, valley, or wady. “River of Egypt” is the Nile (Gen. 15:1818In the same day the Lord made a covenant with Abram, saying, Unto thy seed have I given this land, from the river of Egypt unto the great river, the river Euphrates: (Genesis 15:18); Num. 34:55And the border shall fetch a compass from Azmon unto the river of Egypt, and the goings out of it shall be at the sea. (Numbers 34:5); Josh. 15:4,474From thence it passed toward Azmon, and went out unto the river of Egypt; and the goings out of that coast were at the sea: this shall be your south coast. (Joshua 15:4)
47Ashdod with her towns and her villages, Gaza with her towns and her villages, unto the river of Egypt, and the great sea, and the border thereof: (Joshua 15:47)
; 1 Kings 8:6565And at that time Solomon held a feast, and all Israel with him, a great congregation, from the entering in of Hamath unto the river of Egypt, before the Lord our God, seven days and seven days, even fourteen days. (1 Kings 8:65); 2 Kings 24:77And the king of Egypt came not again any more out of his land: for the king of Babylon had taken from the river of Egypt unto the river Euphrates all that pertained to the king of Egypt. (2 Kings 24:7)). “The river” is the Euphrates (Gen. 31:2121So he fled with all that he had; and he rose up, and passed over the river, and set his face toward the mount Gilead. (Genesis 31:21); Ex. 23:3131And I will set thy bounds from the Red sea even unto the sea of the Philistines, and from the desert unto the river: for I will deliver the inhabitants of the land into your hand; and thou shalt drive them out before thee. (Exodus 23:31)).

Concise Bible Dictionary:

The three principal rivers referred to in scripture are the Nile, the Jordan, and the Euphrates. The word employed for the Nile is yeor, “a fosse or channel”; for the Jordan and the Euphrates the word used is nahar, “a river” always supplied with water. The other streams in Palestine, though called “rivers,” as the Arnon, are torrents running in valleys; for the most part they have water only in the winter, and are then often impassable: these are described by the word nachal. For the symbolical river that Ezekiel saw issuing from the house this latter word is used (Ezekiel 47:5-125Afterward he measured a thousand; and it was a river that I could not pass over: for the waters were risen, waters to swim in, a river that could not be passed over. 6And he said unto me, Son of man, hast thou seen this? Then he brought me, and caused me to return to the brink of the river. 7Now when I had returned, behold, at the bank of the river were very many trees on the one side and on the other. 8Then said he unto me, These waters issue out toward the east country, and go down into the desert, and go into the sea: which being brought forth into the sea, the waters shall be healed. 9And it shall come to pass, that every thing that liveth, which moveth, whithersoever the rivers shall come, shall live: and there shall be a very great multitude of fish, because these waters shall come thither: for they shall be healed; and every thing shall live whither the river cometh. 10And it shall come to pass, that the fishers shall stand upon it from En-gedi even unto En-eglaim; they shall be a place to spread forth nets; their fish shall be according to their kinds, as the fish of the great sea, exceeding many. 11But the miry places thereof and the marishes thereof shall not be healed; they shall be given to salt. 12And by the river upon the bank thereof, on this side and on that side, shall grow all trees for meat, whose leaf shall not fade, neither shall the fruit thereof be consumed: it shall bring forth new fruit according to his months, because their waters they issued out of the sanctuary: and the fruit thereof shall be for meat, and the leaf thereof for medicine. (Ezekiel 47:5‑12)).
God will make His people drink of the river of His pleasures (Psa. 36:88They shall be abundantly satisfied with the fatness of thy house; and thou shalt make them drink of the river of thy pleasures. (Psalm 36:8)); here the word is nachal. In Psalm 46:44There is a river, the streams whereof shall make glad the city of God, the holy place of the tabernacles of the most High. (Psalm 46:4) it is nahar. “There is a river, the streams whereof shall make glad the city of God.” It will never run dry.
