The flood — Thou didst by cleaving the rock, make a fountain and a stream to flow from it, for the refreshment of thy people in those dry deserts. Driedst — Jordan and the Red Sea; for the sea itself; yea, a greater sea than that, is called a river, Jonah 2:3, where the Hebrew word is the same which is here used. And the same title is expressly given to the sea, by Homer, and other ancient writers.
