Nile

Boyd’s Bible Dictionary:

(dark blue). The great river of Egypt, worshipped as a god, famous for its annual and fertilizing overflows and its many mouths. Name not mentioned in scripture, but alluded to as “the river” (Gen. 41:11And it came to pass at the end of two full years, that Pharaoh dreamed: and, behold, he stood by the river. (Genesis 41:1); Ex. 2:3; 7:213And when she could not longer hide him, she took for him an ark of bulrushes, and daubed it with slime and with pitch, and put the child therein; and she laid it in the flags by the river's brink. (Exodus 2:3)
21And the fish that was in the river died; and the river stank, and the Egyptians could not drink of the water of the river; and there was blood throughout all the land of Egypt. (Exodus 7:21)
); “the river of Egypt” (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)); “flood of Egypt” (Amos 8:88Shall not the land tremble for this, and every one mourn that dwelleth therein? and it shall rise up wholly as a flood; and it shall be cast out and drowned, as by the flood of Egypt.

From Manners and Customs of the Bible:

The extent of this calamity will be seen when it is remembered that the waters of the Nile were to the Egyptians then, as now, the great source of dependence for drinking and for culinary purposes. The spring water is hard and unwholesome, wells are seldom found, and rain water cannot be collected because it hardly ever rains. The inhabitants are therefore driven to the river, which all travelers agree in saying furnishes as sweet and wholesome water as can be found in the world. It is at first very thick and muddy, but can be readily filtered. The Egyptians say that “Nile-water is as sweet as honey and sugar.” Great indeed must have been the misfortune when this universal supply of one of the greatest necessaries of life was cut off.
