Ye mountains, that ye skipped like rams,.... Not for joy, but fear; what caused these trembling motions, these violent agitations, and quakings, and movings to and fro like the skipping of rams?
And ye little hills, like lambs? what was it that disturbed you, and put you into a panic, that you skipped like frightened lambs? These questions are put, by a beautiful and poetical figure, to inanimate creatures; the Red sea, the river of Jordan, the mountains of Sinai and Horeb, and the hills about them; to which an answer is turned in the next verse.
