Isaiah 23:3

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 ; .

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 (). 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 (; ; .)

(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 - (.) No city was more favourably situated for commerce.
