Psalms 114:5

"When Israel came out of Egypt, and the house of Jacob from among the strange people" [Psalm 114:1], "Judah was His sanctuary, and Israel His dominion" [Psalm 114:2]; "the sea saw that and fled, Jordan was driven back" [Psalm 114:3]. Think not that past deeds are related unto us, but rather that the future is predicted; since, while those miracles also were going on in that people, things present indeed were happening, but not without an intimation of things future....Some things he has related differently to what we have learned and read there: that he might not truly be thought to be repeating past acts rather than to be prophesying future things. For in the first place, we read not that the Jordan was driven back, but that it stood still on the side nearest the source of its streams, while the people were passing through; next, we read not of the mountains and hills skipping: all which he has added, and repeated. For after saying, "The sea saw that, and fled; Jordan was driven back:" he added, "The mountains skipped like rams, and the little hills like young sheep" [Psalm 114:4]: and then asks, "What ails you, O thou sea, that you fled, and thou, Jordan, that you were driven back?" [Psalm 114:5]. "You mountains, that you skipped like rams; and you little hills, like young sheep?" [Psalm 114:6].

What ailed thee, O thou sea, that thou fleddest?.... What was the matter with thee? what appeared to thee? what didst thou see? what didst thou feel, which caused thee to flee in such haste? Thou Jordan, that thou wast driven back? what is the meaning that thou didst not continue to flow as usual? what was it that stopped thy flowing tide? that cut off thy waters? that drove them back as fast or faster than they came?

What ailed thee, O thou sea? Wert thou terribly afraid? Did thy strength fail thee? Did thy very heart dry up? What ailed thee, O thou sea, that thou fleddest? Thou wert neighbour to the power of Pharaoh, but thou didst never fear his hosts; stormy wind could never prevail against thee so as to divide thee in twain; but when the way of the Lord was in thy great waters thou was seized with affright, and thou becamest a fugitive from before him. Thou Jordan, that thou wast driven back? What ailed thee, O quick descending river? Thy fountains had not dried up, neither had a chasm opened to engulf thee! The near approach of Israel and her God sufficed to make thee retrace thy steps. What aileth all our enemies that they fly when the Lord is on our side? What aileth hell itself that it is utterly routed when Jesus lifts up a standard against it? "Fear took hold upon them there, "for fear of Him the stoutest hearted did quake, and became as dead men.

What ailed thee, O thou sea - The original is very abrupt; and the prosopopoeia, or personification very fine and expressive: - What to thee, O sea, that thou fleddest away! O Jordan, that thou didst roll back! Ye mountains, that ye leaped like rams! And ye hills, like the young of the fold! After these very sublime interrogations, God appears; and the psalmist proceeds as if answering his own questions: - At the appearance of the Lord, O earth, thou didst tremble; At the appearance of the strong God of Jacob. Converting the rock into a pool of waters; The granite into water springs. I know the present Hebrew text reads חולי chuli, “tremble thou,” in the imperative; but almost all the Versions understood the word in past tense, and read as if the psalmist was answering his own questions, as stated in the translation above. “Tremble thou, O earth.” As if he had said, Thou mayest well tremble, O earth, at the presence of the Lord, at the presence of the God of Jacob.

What ailed thee, O thou sea, that thou fleddest?... - literally, “What to thee, O sea,” etc. That is, What influenced thee - what alarmed thee - what put thee into such fear, and caused such consternation? Instead of stating the cause or reason why they were thus thrown into dismay, the psalmist uses the language of surprise, as if these inanimate objects had been smitten with sudden terror, and as if it were proper to ask an explanation from themselves in regard to conduct that seemed so strange.
