as a flood - (Jer 47:2; Isa 8:7, Isa 8:8; Dan 11:22). The figure is appropriate in addressing Egyptians, as the Nile, their great river, yearly overspreads their lands with a turbid, muddy flood. So their army, swelling with arrogance, shall overspread the region south of Euphrates; but it, like the Nile, shall retreat as fast as it advanced.
