That saith to the deep, be dry,.... The Targum is,
"that saith to Babylon, be desolate;''
and most interpreters, Jewish and Christian, understand it of Babylon, which was situated in a watery place, by rivers of water, particularly the river Euphrates, and in a low valley:
and I will dry up thy rivers; some think the allusion is to the stratagem of Cyrus, made use of, under a divine direction, to drain the river Euphrates, and make it passable for his army; by which means he surprised the city of Babylon, and took it: though others think it refers to the drying up of the Red sea and the river Jordan, which are proofs of what God can do, and a periphrasis of his power.
