And by great waters the seed of Sihor, the harvest of the river, is her revenue; and she is a mart of nations. By great waters - the wide waters of the sea.
Seed - the grain, or crop, as in 1 Samuel 8:15; Job 39:12.
Of Sihor - literally, dark-coloured, from shahhar, to be black; applied to the Nile, as the Greek, melas, anciently Kmelas: Latin, melo (Servius, 'Georgics,' 4: 291; 'AEneid,' 1: 745), to express the dark turbid colours given to its waters by the fertilizing soil which it deposits at its yearly overflow (Jeremiah 2:18). The name Nilus is akin to the Sanskrit, Nilah, blue. In hieroglyphics the name of the country is KEM - i:e., black. In painted sculptures the Nile-god is coloured red during the inundation, and during the rest of the year blue.
The harvest of the river - the growth of the Delta; the produce due to the overflow of the Nile: Egypt was the great granary of grain in the ancient world (Genesis 41:1-57; Genesis 42:1-38; Genesis 43:1-34.)
(Is) her revenue. Tyrian vessels carried Egyptian produce, gotten in exchange for wine, oil, glass, etc., into various lands, and so made large profits.
And she is a mart of nations - (Ezekiel 27:3.) No city was more favourably situated for commerce.
