Shall fade away, i.e. shall wither and decay in their hopes and strength. Be afraid, i.e. shall come trembling; one verb being put for two, as Psalms 22:21, thou hast heard me, i.e. having delivered me; and Psalms 42:1, panteth, i.e. panting hasteneth; and in many other places. Out of their close places; out of their strong holds, where they shall lurk and keep themselves for fear of me, and whence they dare not stir without trembling. Or, for (as the particle mere is oft used) their close places, i.e. lest I should assault and take them.
