Dark; blue, not found in Scripture, but frequently referred to in the Old Testament under the name of Sihor, i.e., “the black stream” (Isa. 23:3; Jer. 2:18) or simply “the river” (Gen. 41:1; Ex. 1:22, etc.) and the “flood of Egypt” (Amos 8:8). It consists of two rivers, the White Nile, which takes its rise in the Victoria Nyanza, and the Blue Nile, which rises in the Abyssinian Mountains. These unite at the town of Khartoum, whence it pursues its course for 1,800 miles, and falls into the Mediterranean through its two branches, into which it is divided a few miles north of Cairo, the Rosetta and the Damietta branch. (See EGYPT.)
Nile
Egypt lived by its river, and the prophets knew it. The name Nile does not appear in the King James Bible, but “the river” of Egypt does, and so does Sihor, a word often taken to mean the same waters. In Isaiah 19 the river “shall be wasted and dried up” and everyone who depends on it mourns: the fishers, the flax workers, the weavers. Ezekiel pictures Pharaoh as a creature pulled from his own rivers. The message is that no power, however well supplied, stands apart from God. Read Isaiah 19:5-10, noting how a nation’s livelihood is painted in small trades.
10 verses
Isaiah
And the LORD shall utterly destroy the tongue of the Egyptian sea; and with his mighty wind shall he shake his hand over the river, and shall smite it in the seven streams, and make men go over dryshod.
And the waters shall fail from the sea, and the river shall be wasted and dried up.
And they shall turn the rivers far away; and the brooks of defence shall be emptied and dried up: the reeds and flags shall wither.
The paper reeds by the brooks, by the mouth of the brooks, and every thing sown by the brooks, shall wither, be driven away, and be no more.
The fishers also shall mourn, and all they that cast angle into the brooks shall lament, and they that spread nets upon the waters shall languish.
Moreover they that work in fine flax, and they that weave networks, shall be confounded.
And they shall be broken in the purposes thereof, all that make sluices and ponds for fish.
And by great waters the seed of Sihor, the harvest of the river, is her revenue; and she is a mart of nations.
Jeremiah
And now what hast thou to do in the way of Egypt, to drink the waters of Sihor? or what hast thou to do in the way of Assyria, to drink the waters of the river?
Ezekiel
But I will put hooks in thy jaws, and I will cause the fish of thy rivers to stick unto thy scales, and I will bring thee up out of the midst of thy rivers, and all the fish of thy rivers shall stick unto thy scales.
