Psalms 114:5-6

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.
