Nahum 2:6 - Wesley's Explanatory Notes

The gates — Of the city toward the river. The rivers — Of the Tigris, upon which Nineveh stood. Dissolved — While the Chaldeans besieged Nineveh, a mighty deluge overthrew the walls of Nineveh, by the space of twenty furlongs, through which breach the besiegers made their entrance. Dissolved — As if melted, it shall drop to pieces.
