To go into the clefts of the rocks, And into the crevices of the crags, From before the terror of the LORD, And from the glory of His majesty, When he ariseth to shake mightily the earth.
Ibn Ezra on Isaiah
סעפי. Branchlike pieces projecting from the rocks, where people can hide themselves.27Comp.סעיף branch. A.V., The tops of.
Ibn Ezra on Isaiah
לערוץ To be mighty.28A. V., To shake terribly. Root ערץ ; comp. עריץ mighty. According to others, it is a transitive verb, meaning to terrify; אל תערץ (Jos. 1:9) has, perhaps, the same meaning, the word לבך thine heart, being supplied—do not terrify or discourage thine heart—and עריץ (29:20), is then a transitive adjective, terrible, like אימים (Gen. 14:5), the terrifying ones.29A.V., The Emims.
