Reference: River Of Egypt
(1.) Heb nahar mitsraim, denotes in Ge 15:18 the Nile, or its eastern branch (2Ch 9:26). (2.) In Nu 34:5 (R.V., "brook of Egypt") the Hebrew word is nahal, denoting a stream flowing rapidly in winter, or in the rainy season. This is a desert stream on the borders of Egypt. It is now called the Wady el-'Arish. The present boundary between Egypt and Palestine is about midway between this wady and Gaza. (See Nu 34:5; Jos 15:4,47; 1Ki 8:65; 2Ki 24:7; Isa 27:12; Eze 47:19. In all these passages the R.V. has "brook" and the A.V. "river.")
(1) Nehar Mitsraim (Ge 15:18); "the Nile".
(2) Nahal Mitsaim (Nu 34:5; Jos 15:3-4,47; 1Ki 8:65; 2Ki 24:7); "the torrent of Egypt": see above nahal, "a stream flowing rapidly in the rainy season, then drying up", inapplicable to the sluggish Nile ever flowing. The Rhinocorura or Rhinocolora (so Septuagint of Isa 27:12) on the sea coast, a wady and torrent running into the sea two or three days' journey from the nearest branch of the Nile. Now wady el Arish. Though not in Egypt, it was the last torrent of any raze on the way toward Egypt from the N. In Jos 13:3, "from Sihor which is before Egypt," the same torrent is marked as Israel's southern boundary, as the entering in of Hamath is the northern (Nu 34:5,8). The Nile was not "before" (i.e. east of) Egypt, but flowed through the middle of the land; so 1Ch 13:5. Shihor, "the black river," is the Nile's designation in De 23:3; Jer 2:18.
River of Egypt.
1. The Nile.
2. A desert stream on the border of Egypt, still occasionally flowing in the valley called Wadi-l-'Areesh. The centre of the valley is occupied by the bed of this torrent, which only flows after rains, as is usual in the desert valleys. This stream is first mentioned as the point where the southern border of the promised land touched the Mediterranean, which formed its western border.
In the latter history we find Solomon's kingdom extending from the "entering in of Hamath unto the river of Egypt,"
and Egypt limited in the same manner where the loss of the eastern provinces is mentioned.
