Psalms 114:3-6

The sea saw it, and fled Saw that God was present with and among them in an extraordinary manner, and therefore fled; for nothing could have been more awful. Jordan is driven back At the appearance of the divine glory which conducted them. “Although forty years intervened between the two events here mentioned, yet, as the miracles were of the same nature, they are spoken of together.” The mountains skipped like rams Horeb and Sinai, two tops of one mountain, and other neighbouring hills and mountains. The same power that fixed the fluid waters, and made them stand still, shook the stable mountains, and made them tremble; for all the powers of nature are at the command and under the control of the God of nature. Mountains and hills are before God but like rams and lambs; even the largest and the most rocky of them are as manageable by him as the sheep are by the shepherd. The trembling of the mountains before Jehovah may shame the stupidity and obduracy of sinners, who are not moved at the discoveries of his glory. What ailed thee, O sea, that thou fleddest? What was the reason, or for what cause was it, that thou didst, with such precipitation, retire and leave the middle of thy channel dry? Why didst thou, O Jordan, run back toward thy springs? Ye mountains, that ye skipped, &c. Whence this unusual motion? Why did you leap like affrighted rams or lambs, as if you would have run away from the place where you had so long been fixed?
