the assault upon the city wall to the capture of the city itself (Nah 2:6). The opened or opening gates of the rivers are neither those approaches to the city which were situated on the bank of the Tigris, and were opened by the overflowing of the river, in support of which appeal has been made to the statement of Diodor. Sic. ii. 27, that the city wall was destroyed for the space of twenty stadia by the overflowing of the Tigris; for “gates of the rivers” cannot possibly stand for gates opened by rivers. Still less can it be those roads of the city which led to the gates, and which were flooded with people instead of water (Hitzig), or with enemies, who were pressing from the gates into the city like overflowing rivers (Ros.); nor even gates through which rivers flow, i.e., sluices, namely those of the concentric canals issuing from the Tigris, with which the palace could be laid under water (Vatabl., Burck, Hitzig, ed. 1); but as Luther renders it, “gates on the waters,” i.e., situated on the rivers, or gates in the city wall, which were protected by the rivers; “gates most strongly fortified, both by nature and art” (Tuch, de Nino urbe, p. 67, Strauss, and others), for nehârōth must be understood as signifying the Tigris and its tributaries and canals. At any rate, there were such gates in Nineveh, since the city, which stood at the junction of the Khosr with the Tigris, in the slope of the (by no means steep) rocky bank, was to some extent so built in the alluvium, that the natural course of the Khosr had to be dammed off from the plain chosen for the city by three stone dams, remnants of which are still to be seen; and a canal was cut above this point, which conducted the water to the plain of the city, where it was turned both right and left into the city moats, but had a waste channel through the city. To the south, however, another small collection of waters helped to fill the trenches. “The wall on the side towards the river consisted of a slightly curved line, which connected together the mouths of the trenches, but on the land side it was built at a short distance from the trenches. The wall on the river side now borders upon meadows, which are only flooded at high water; but the soil has probably been greatly elevated, and at the time when the city was built this was certainly river” (see M. v. Niebuhr, Geschichte Assurs u. Babels, p. 280; and the outlines of the plan of the ground oh which Nineveh stood, p. 284). The
