The sea is come up upon Babylon: she is covered with the multitude of the waves thereof.
The sea is come up upon Babylon - "the sea" - i:e., the host of Median invaders. The image (cf. Jeremiah 47:2; Isaiah 8:7-8) is appropriately taken from the Euphrates, which, overflowing in spring, is like a "sea" near Babylon (Jeremiah 51:13; Jeremiah 51:32; Jeremiah 51:36).
