The valley of the Nile was the field for sowing and reaping.
The ships of Tyre trafficked far and wide, and by purchase or by barter the corn supplies of Egypt were fetched in to fill the barns and granaries of the merchant city, and were thence resold with profit to many nations. The harvest of the Nile most accurately describes and stands for all the resources and the wealth of Egypt, which depend entirely upon the Nile. This river brings down from the mountains of Abyssinia a great quantity of decayed vegetable matter and rich alluvial deposit, which in flood time it spreads over the land. A failure in the rise of the Nile means famine in Egypt, and it was lately computed that one foot difference in the height of the annual flood makes a difference of £2,000,000 to the income of the country. So little in this respect have things changed since the days of Isaiah. (P. T. Bainbrigge, M. A.)
The harvest of the river
We need not, however, restrict the term to the importation of corn. The harvest of the river was the merchandise of the world, which the ships of Tarshish conveyed to the city of the isle--Tyre. The harvest of the river, then, is the commerce of the city built upon its banks. God is equally the God of the harvest of the river as He is the God of the harvest of the field, and though He made the country He ordained that men should form themselves into communities and dwell together in cities, and He has laid down laws for their guidance as members of a great society which must be followed, that order may be maintained and prosperity achieved. The merchant is as much engaged in doing God’s work as the farmer is. There may not be so much romance and poetry about his occupation. But God may be glorified in the fires as well as in the green fields and the pleasant woods. It is He who assigns to every man his proper place--implants within him a desire to do his duty in his appointed sphere of action, and so contrives that while a man does his duty and provides for his own interest and welfare, he by so doing contributes at the same time to the happiness and well-being of all. (W. Rogers, M. A.)
God the great World-Provider
When the Shah of Persia some few years ago visited this country, he was taken through the docks down the river, and while contemplating the great harvest reposing on its bosom, and witnessing the crowds of people eager to see the Eastern potentate and to do him honour, he asked a pertinent question of the nobleman who accompanied him. It was this: “How are these vast multitudes fed?” It is a question which showed the thoughtful intelligence of the barbarian, but it is one which few pause to ask, and which few are able to answer, because few look beyond the surface and attempt to unravel the great mystery by which we are enshrouded, and recognise the agency of the invisible One in all the affairs of men. (W. Rogers, M. A.)
